The supercharged 6.2L V8 LT4 gasoline engine can be found in a variety of high-performance GM products, including the Cadillac CT5-V Blackwing, the Cadillac Escalade-V, and the now-discontinued sixth-generation Chevy Camaro ZL1. Offering impressive performance via high-horsepower ratings and a fat torque curve, the LT4 is a fantastic motor for just about any go-fast application, which may lead some enthusiasts to wonder why it isn’t available in other full-size GM SUVs, such as the Chevy Tahoe, Chevy Suburban, GMC Yukon, or Yukon XL, or GM pickup models, such as the Chevy Silverado and GMC Sierra. Now, GM Authority has an answer.
The reasoning behind all this starts with where the engine is produced. Every LT4 V8 is assembled by hand at GM’s Performance Build Center in Bowling Green, Kentucky, and as a result, it has constrained production volume compared to mass-produced GM V8 engines like the LT1, LT2, and L87, among others.
As a result of the constrained production, GM wants to maximize the profitability of every LT4 sold. If General Motors were to offer LT4-powered variants of the Chevy Silverado, Chevy Tahoe, or Chevy Suburban (possibly with an SS badge), they would need to be less expensive than the Cadillac Escalade-V, simply by the virtue that they were Chevy products and not Cadillacs. A LT4-powered Chevy Silverado, Tahoe, or Suburban would likely start around $100,000, as compared to the Escalade-V’s starting price of $152,295. The same logic could also be applied to GMC.
Currently, GM sells every single supercharged Cadillac as quickly as it’s built, so The General might as well maximize profits on every single one. Plus, not only is it difficult to accelerate LT4 production, but Cadillacs deliver on profit maximization given their premium placement.
“Sources tell us that GM sells every LT4 they can make,” says GM Authority Executive Editor Alex Luft. “In other words, production volume of the engine is limited, and it’s simply good business sense to squeeze as much profit as possible from an item that’s limited in availability.”
With the departure of the sixth-gen Camaro, the CT5-V Blackwing remains the only GM car (rather than truck or utility vehicle) that makes sense for LT4 power. Some may point to the Corvette C8, but the C8 was never developed to cradle any other Small Block V8 beyond the naturally aspirated 6.2L LT2.
That all said, any enthusiast driven enough to drop an LT4 under the hood of their Silverado or Tahoe can still purchase the LT4 as a crate engine, starting around $18,000 new. The aftermarket is also a possibility, with companies like SVE and Hennessey offering supercharger upgrades for a variety of V8-powered GM products, including the Silverado, Sierra, Suburban, Tahoe, and Yukon.

This company is souless
Why doesn’t GM just build a forced induction l87? They’re all ls based engines at the end of the day
No Toyota is soulless dropping a proper V8 truck if a V6 turbo the hybrid is nice but why not make a V8 hybrid… and it’s not just Toyota not Dodge RAM whatever they call themselves this year dropped the V8 not just from cars but from full sized trucks as well it’s going to be hilarious when that twin turbo fix it again Tony Italian V6 breaks from stress of doing truck stuff like hauling and towing. GM is the only company working on updating their V8 engines…why?? Maybe they know something. But this doesn’t end here next it will be the v6 that goes extinct just like the V8 is doing now.
Weird Toyota still offers a V8 under the hood of their compact Lexus IS sedan. In addition to a V6 under the hood of the Camry until 2025.
Not to mention Toyota’s 5.7 V8 is much much more reliable than any V8 GM makes today.
Maybe as reliable but not more than the non afm LS V8s in express vans……
Non-afm LS’s were/are bulletproof. I just replaced a failed cam (and lifters) in my L86 with afm-delete parts – after 10k miles my mileage is UP 0.2 mpg’s compared to with afm. Total junk.
Same with me, 2012 Tahoe, AFM eliminated, gained 0.2 mpg on short trips, much more enjoyable to drive.
You drive weird then. Study shows AFM increases milage and reduces wear in almost all scenarios,,,, except when people drive erratically and the system is switching constantly. DFM doesn’t have that problem
The Toyota 5.7 is more Ford than GM. DOHC, 24.valves.
LOL Toyota V8 engines get sludge and they are more reliable. Have you read all the press on Toyota V8 engines being terrible ?
Zack Toyota just has the name it doesn’t help that their the darling do no wrong of consumer reports, they have issues but you never hear about them as much I think they fix and cover it up right away.
Better that Toyota fix them and shut down the bad publicity than ignore them or claim that they are not really defects because it was only a design defect.
the 5.7 IFORCE V8 has issues such as cam tower leaks, and AIP failures. Expensive problems actually. You do not hear about all of them because very less Toyota Trucks are produced.
Weird because the 2024 Tundra doesn’t have a 5.7L option
Pity actually considering the Nissan Titan and the related Patrol Y62 both have a 5.6L V8 for the 2024 model and had for the 2022 (the Titan will be discontinued unfortunately). The Titan and Patrol V8 is infinitely more reliable than the 3.4 TT in either the Land Cruiser 300 or the Tundra at the moment, considering the main bearing issues which are still not yet sorted. Toyota has never issued a recall for it yet unlike the camshaft issues in the 5.7L (recall or not, the main bearings are a serious problem). And the Titan V8 has been in production for 20 years (same as the GM 6.0 L96 V8), and is a time tested design.
Yes because Toy doesn’t offer a V8 in their what they call trucks anymore….
The 5.7 in the tundra is not a GM design. It would’ve taken you 2 seconds to Google search this and save your self from looking dumb.
BS. I don’t like Toyota but they’re making exciting affordable products. GM is not.
GM is where Toyota was 15 years ago. Boring, uncompetitive (most vehicles) that maximize profit. Only difference is those Toyota’s were stupid reliable due to being so old and GM removed reliability for things like 1.3l 3 cylinders.
GM has all the parts to make some really cool stuff. But they chose not to.
It’s another in a consistent string of bad decisions by GM leadership. The engine costs – at the very most – $6k more to build than an LT1, yet they charge $50k more for it in an Escalade. With over $40k of net profit per ENGINE, an intelligent leader would build an additional production line (or two or ten) to build more engines so they could sell more vehicles with that engine. Even if the adder in a Silverado or Yukon were more modest ($20k??) the incremental profit is ridiculous. But nooooo… let’s focus on more electric BS that nobody wants.
Another bad GM decision to take advantage of there place in the market
When your customer have been begging for years of such engine
You can’t make this engine on another line or make another shift for this when you have known for years about it, just look at Ram and the Hellcat engine bringing it to the market they took the risk and paid off remarkably because the demand was there.
GM has made this engine for years and you can’t tell me they don’t know how to make the engine more affordable
GM has invested on the wrong projects constantly
Don’t get me wrong I love there vehicles especially large body on frame vehicles but
I’m wondering what they have invested on all this years the competition has invested on future engines Ram 3.0L I-6 TT/ Ford 3.5l V6 TT/ Toyota 3.4L V6 TT
GM has still not come up with nothing new except for
The 3.0L I-6 TD truck engine which was good decision and is the only one left in the class so there’s sign they can do really good job but All this engines have been in the works for years
I hope there not going to push for this all electric movement again look at Ford they can’t sell this all electric f150 trucks it just doesn’t make any sense maybe for woke law makers that wants credit for the movement that no one normal wants
They did not come up with anything new, like Nissan for example in the case of the Titan since these engines do not need to be changed and these trucks still sell in large numbers. Their pushrod design dates to 2014, so it is 10 years old.
GM knows that a power increase could have come at a cost, so chose not to do it for 2019.
Isn’t it more profitable to start an automated line in Tonawanda, drive down the production cost, then make bigger margins on the V line, as well as extra truck sales??? These MBA’s they got must have failed algebra in high school.
No GM leadership made it to class on Business 101 day.
Betting an automated line would be building better quality engines than those they claim are “hand-built” ! Robots eliminate possibility of human error and don’t have good days and bad days.
No hand built is better then mass produced by robots or humans because they are limited production and you don’t need a whole crew to build one…the same is true in anything back in the old days of mass production things where still limited take for example 1950s model trains or cars once the hobby shop or car dealer ran out of or sold a particular model you had to order what you wanted and wait . They used robots in the 80s and 90s and things still went wrong.
Why not offer it in the chevy as a high dollar option? I don’t understand how does ram get the Hellcat inside everything!
Sweet dreams, indeed. But government motors won’t even allow anything bigger than the cracking 2.7 4cyl in a full size short bed regular cab.
It’d be a slam dunk to market an SS 5.3 V8 with the dual mode exhaust. All parts bin stuff. Easily under 50K and they’d sell.
Escalade V is pure parts bin, and it only took GM 15 years to bring it to market. Nah…I guess a V8 in a SWB regular cab is too controversial. It’s not like it’s ever been done before.
And this is exactly why the ZR2 Silverado is no big deal compared to the TRX and the Raptor R. Not enough power or “Thrill factor.”
To all the naysayers. Everyone is forgetting about one cost to gm selling a vehicle with an LT5. CAFE drop. Take a look at the MPG of a V-slade. And then lookup what every tenth of an mpg that you miss the CAFE number costs the manufacturer. It’s not just the price of the engine, it is the penalty for putting it into something. So they put them into very high profit vehicles. Completely logical in today’s real world of CAFE. I doubt they get dinged for the crate engines, so they sell for a reasonable number. I’ve got an SC engine in my wagon. Mileage is awful. Just part of SC engines. Also had a v6 T-BirdSC. That SC V6 got the same mpg as Ford’s V8 in the TBird. There was talk of a electric turbo system that looked promising with better mileage. Looked like a great idea, but I think must have been impossible to build reliable and inexpensive as I’ve never seen it in production.
At least someone here gets it. Thank you.
Bull. Dodge sells TONS of V8’s in cars, SUV’s, Jeeps, and trucks – 5.7’s, 6.4’s and supercharged 6.2’s across the whole spectrum. Maybe their leadership is just smarter than GM’s.
They WERE. Stellantis’ frail looking European CEO is all in on the WEF agenda, too.
I’ve lifted this post from a hellcat forum. Should help explain why. And that 1.4-1.8B was going to tesla. Ever wonder how they make money? Credits, not cars. And guess who is championing ever higher mpg fines? Lonnie. “The problem with this are the fines. Right now, Dodge is paying 1.4-1.8 billion per year in carbon offsets. When you average out the per unit cost over all the cars they make, it comes out to something like $3,500-$4,500 per vehicle in carbon offsets. The EPA closed the carbon offset loophole starting 1 Jan 2024. The fine for running afoul of the CAFE standards would be close to $50,000 per vehicle sold (it’s variable per how far off the car is from the standard… some would be fined 25-30k, and cars like DDHCs might get fined 60k). And then, it isn’t a “pay us the fine and keep going.” It’s a pay the fine and if you don’t comply, we’ll shut your business down type of fine. So, while Dodge might be able to squeak by a few months with fines, eventually they’d be declared illegal for sale. I’m not as well versed in this as to how long it would take for them to lose their right to sell cars, but that would be the next step.”
Gov’t regulators run amok.
So…..
LT5 2500 HD, suck on that GOV.
HD’s are cafe exempt. GM MBA’s are still fools if I can figure this out
HD’s fall into CAFE in the next few years. You can’t keep Big Government out of way forever.
It is amazing how many don’t get that auto makers just can’t do it all or what ever they like.
GM is smart as they will make more money on the high end product vs a truck.
They could raise the price of the ZR2 to the Escalade price to make the same money but would you pay six figures.
Folks this is no longer the 60’s where they can just pop an engine in anything.
Cost and profits matter.
While Ford may have a Raptor it has done nothing to improve stock prices. stellantis Is not exactly moving in a positive way either with dropping sales and stagnate sales.
This is about sustainability of the company as a whole not satisfying a few people on the web that could not afford what they want in the first place.
Itis about maxing return on the dollar.
I think what you meant to say is, “it’s about maximizing return on the dollar within the government’s regulations. ” Change CAFE and California rules, and a different optimization results.
CAFE and EPA hae very little to do with this. Trucks actually help their overall umbrella coverage. This is just a foolish error on GM top brass, as usual.
To build more engines would mean a new and larger plant. It would mean more workers that are very expensive. These engines sre hand assembled by one person and signed.
The scale how these are built are much different than Chrysler.
Also Chrysler was making so much on them they just killed them while GM is working yo bring a new V8 to market.
You need to apply more yo this than just what you think you know.
Also add up the total production of each truck and you will find there fewer sold than you believe.
At the end of the day it is all about profit and if it were that easy money the others both would have higher stock prices.
I think it was smart keeping the ZR2 and AT4X prices as low as possible. I don’t think I would see as many around town if it was priced in a higher bracket.
This argument doesn’t make sense now that GM in theor infinite wisdom, has yet again dropped the Camaro, and there are engines built on this line for that car. So, continue to make the same amount of engines, but place them in the trucks or SUV that the customers want.
The other issue is that the Camaro with this engine do not cost over $100k, but many SUV/Truck trim leels are already close, if not higher than that.
This is just another example of someone at GM missing the mark and then spewing nonsense to cover their a$$.
But if money was an issue, then thry could EASILY make an SS, which should be a single cab, 2wd or even AWD and basically stripped of a lot of creature comforts that a Denali or Chevy top trim has.
It isn’t that they can’t, it is simply they won’t. They’re too busy losing Millions by cowering to the Government boot and building (and Failing) electric vehicles that no one is buying.
Dodge has an equivalent in their entire line, heck, even JEEP has super high performance engines. They ALL sell out. Don’t tell me it won’t work for GM.
It makes sense if you use the real numbers vs just assuming.
FYI the EV thing is a real issue and what will you sell when the politicians enforce the laws and you have no product that fit?
GM rushed to meet regulations in the 80’s how did that turn out?
I feel like they’re age missing an opportunity to release a GMC Denali street truck and a Chevy high country off-roader high performance variants. This is also true in the canyon/Colorado space. No necessarily the supercharged 8, but it would probably sell pretty well to the zr2 and then a modern day sysclone/typhoon.
That’s another thing, all these SUVs and they never expanded to build a real “small” SUV on the small truck platform.
I also feel Cadillac shows how constrained the choices for cars are. Buick needs diversity but I feel it’s just a backdoor to ease Americans into China assembled vehicles. The Malibu due for refresh but was picking up momentum… The bam…only offered with an anemic 1.3 L… Dropped the wonderful 2.0.
Cadillac’s are rebadged Chevy’s. If you think otherwise, you are entitled to your opinion.
Lexus is a rebadged Toyota your point?
SUVs yes. But the cars are their own platform. The previous ATS and Camaro did share their platform. Was hopeful next Gen Camaro would do the same. Camaro.a 2 door coupe not typically cross shopped with luxury sedans.
I don’t buy the excuses. GM could easily produce a limited number of ZR2 and AT4X models with the LT4. Especially now that Camaro will no longer be around in Ice form. I guarantee they would fly off the lot regardless of price.
GM is extraordinarily adept at wringing the last cent out of stock price by absolutely maximizing the profitability of the company. Unfortunately, the talent pretty much ends there. The LT4 decision, while it may be great for profit, does absolutely nothing to enhance the image or desirability of GM products. The Cadillac’s with the LT4 appeal to a very small percentage of the population and the two sedans with the LT4 are boring, non-descript products when equipped with anything but the LT4. The Escalade V is nothing special, an Escalade with the most powerful engine the General makes to give Caddy something in the price range of Range Rover and M/AMG German SUVs. Now that the Camaro is again, dead, GM has zero for the enthusiast to aspire to. An LT4 Tahoe SS or Silverado at say a 10k premium over the standard version would absolutely drive more traffic to Chevy showrooms and likely lift non-LT4 sales as well. Even better, how about a LT4 version of the GMC Canyon as a reboot of the Syclone from ’91. That would get people talking about something more that the recalls plaguing this model. GM really needs something besides Corvette to light enthusiast fires and create a pipeline of new prospective owners. If they think a new Traverse with a 4 banger or a 120k Hummer EV truck will do that, they’re badly mistaken.
wjti, with your post (no offense at all, and not trying to be a d***) there needs to be an option for an “in between” thumbs up and thumbs down! This post has very good points that are spot on (to me at least) and then the thumbs down comments….you had me agreeing and disagreeing so many times! Lol
I understand wanting to maximize profits, but if the demand is there they could still do it. No particular reason the LT4 has to be hand-built other than low-volume. It always blew my mind how much they used to reserve the 6.2 to only specific high end models as an upcharge option, when it’s nearly identical design and materials wise to the 5.3, just different dimensions. So the manufacturing costs are gonna be nearly identical IF they matched the volume. And for that matter, the 5.3 has plenty of power especially with a 10spd for 1500 trucks and SUVs, so why not put it in midsize trucks as a premium option? Or in cars, I always wondered why they didn’t make an affordable V8 Camaro with the 5.3 for people who didn’t need the utmost power but still wanted a V8, woulda sold like stink.
So now they’re laughing all the way to the bank with their Caddy profits, when they could be going after the Raptor/R and TRX or whatever they’re gonna call the Tropical Depression (ok “Hurricane”) version. And I bet you’d have a lot of police and private security sales of LT4 Tahoe’s and Suburbans. I’m sure executive security services can buy the Vs but a $150k+ Caddy doesn’t really fit your local police department.
Sometimes GM is no fun. Make it available as a special offer item in the Silverado.
That may be the reason they fed you but it’s BS. GMA should no better than to take the spoon feeding
Guess it’s another saying of not cannablizing the sales of Escalade V. Got it
Exactly. No one would buy the Cadillac if the Chevy were mechanically identical and 30K cheaper.
JERKS…..THERE ARE THOUSANDS OF US WHO HAVE BEGGED GM FOR A SPORTS TRUCK FOR YEARS. SS MODEL W/ LT4 WOULD MAKE YOU GUYS LOTS OF MONEY……JERKS !
If you are willing to drop V-slade kind of money on a sports truck, just get a crate engine (18K) and have someone drop it in. Your still less than a V-slade I think. My dealer gets around 170 for them. And they don’t last long even with the 20K “adjustment”.
That’d be pretty stupid when Ford will sell me a Raptor R or Ram a TRX for much less. And it’s a far superior truck with full warranty to the GM product
If he was “begging” gm to do it, for whatever reason that is what they want. If they are willing to part with V-slade kind of money to get what they want, ie not an Raptor or RAM, then it can be had. And maybe not even V-slade money. 18K for a motor and I don’t know what a shop would charge to drop it in. Maybe not that much, should go in pretty easy as I think it has the same footprint as the regular 6.2. I doubt gm does that much to drop it into a slade, and the engine compartment should be very similar.
They could easily make a limited run which collectors would buy at a much higher price. But what ever happened to big engines in light cars? Heavy trucks defeat the purpose of performance. So your 150k SUV now goes as fast as a 50k naturally aspirated Camaro. So what.
An LT4 doesn’t just drop into a truck. Mechanically, yes, but ECM and wiring differences are a nightmare, as is calibration. Just go to Callaway and you get a supercharged variant with factory warranty.
I bought the LT4/10L90E from a wrecked 2018 ZL1 Camaro to install in my 1970 C10. It’s definitely more expensive than going with an LSA or LS9 for supercharged power, but I wanted a ton of power and I wanted the 10 speed that can handle it, so it’s worth it to me. You can’t do a 10l90 with anything but a gen 5 currently. Standalone harness are 3-4k and the accessory drive to get power steering and A/C working are another 3k. Costs I didn’t consider when I bought the powertrain. But when it’s all said and done it’s going to be an amazing truck.
One website – lsaconversion.com
Been doing lt4 conversions way longer than anybody – Cars,Trucks and more
GM makes the V8 engine in the Toyota Lexis and prior GM made the V8s in the Toyota pickups! That’s why these V8s are so reliable!
Thanks Marcus so the iforce V8 was/is a GM product that’s Awesome and yes GM does make a very reliable v8 I had an ls1 in my 2002 Camaro Z28 I beat on that car and it never stopped running. One of the best cars I ever owned as far as being near bulletproof.
The reason is everything in the drivetrain of their new trucks are junk…it would never handle the power ….so your better off buying a budget 2wd truck that they offer and make your own…either a crate engine from GM or a junk yard LT4….either way GM has tanked…their product is $hit…my past GMs were (2) 86 Monte Carlos one was an 88 SS….Chevy Celebrity… currently I own a 00 Camaro SS, 16 Silverado 2500 and my wife has a 19 Acadia…the Acadia is the highest sticker price vehicle and the cheapest feeling one out of everything I have ever owned. My Camaro is more put together with its “cheap 90s plastic feels” that car has also been bulletproof and more reliable than anything I have owned and I have had that for 22 yrs…I am a die hard Chevy guy from the beginning and it’s very sad to see where it’s headed….other family vehicles include 2 more Silverado 2500s, equinox, traverse…62 vette… and countless other past chevys in the family
Chevrolet dropped the ball on performance trucks. I jumped ship and purchased a 2019 F150 Shelby Supersnake “green”, for the California CARB market. Purchased the 3 liter Whipple superchargerCARB certified and had it installed at Galpin Motorsports, while maintaining my factory warranty. For a bit under 90k I own a 775hp pickup truck with enormous power. Could not do that with any GM truck in California.
GREED!!! That’s what it comes down too. Plain and simple. They could drop the LT4 in a Silverado SS, 10 speed, dual exhaust, paddle shifters, lowered stance, 22 inch wheels in regular or crew cab configuration and SELL every single one of them at $50k for single cab and $60k for the crew. Mary and GM are ignorant and greedy.
50k for all of this “SS Silverado upgrades” does that include the truck also? Or only the extra amount for an lt4 with said upgrades? You really are dreaming just a bit…although that would be an amazing dream.
@Maroman1
YES, $50k for a single cab!!! That’s a bench seat, and usually room for only 2 people. Are you kidding me….You obviously don’t read for comprehension!!
Maybe in 2012 they could sell them for $50k. What you’re talking about would be worth over $70k!
The article is interesting, but not complete.
GM basically has more CUSTOMERS who want a V8 engine like Ford, Stellantis and other OEMs from Japan, Korea and Germany!!!
That’s why GM is also building the LT5 engine in new special vehicles, especially in Cadillac V-Blackwing variants.
In addition, of course, as an OEM you have to meet the federal government’s CO2 requirements and that’s why LT5 engines are no longer produced and installed in other GM vehicles ex works!!!
Logical or not???
The tuners love GM vehicles and therefore have a perfect V8 basis to assemble and sell the superchargers.
The GM V8 engines – what’s special about them:
I think YOU already know that the GM V8 engines are and have always been the technically best V8 engines and the cheapest V8 engines that customers want and buy. The former high-tech GM 4.2L Biturbo Hot-V Blackwing engine was very interesting, but GM customers didn’t want that engine and overall it wasn’t any better than the LT5 engine!
Technical development from V8 to V6 at other OEMs:
Now at Stellantis – i.e. Dodge – the “Hemi V8” has not been further developed in the last 20 years and is technically outdated compared to GM V6/V8. The Hurrican 3.0L Biturbo is technically complex – a copy of the BMW S58 Biturbo engine – but it is neither more ecological nor technically better than the “ancient HEMI 5.7L / 6.4L V8. The Stellantis engineers also know that, but the big Stellantis boss just wanted this little inline 6. So technical nonsense, but a highlight for marketing & the media???
EVER NO!!!
The pickup trucks are built for hauling and towing, so those of us that use them specifically for that need a strong and reliable engine that will get the job done. The reliable non DI V8 gasoline engine with six or eight speed transmissions is the favorite over the small cracker jack engines with turbos and ten speed transmission.
Except the GM V8 has had numerous reliability issues. Many stemming from the afm mode. It wasn’t DI that killed GM V8 reliability. It was afm.
EXACTLY!
AFM does not kill every single one. Bad maintenance and neglect, no matter how much you disgree does kill them.
BS! I have run exclusively Mobli-1 oils and top tier filters, servicing at or below prescribed intervals, never abusing, never towing – and I’ve lost cams/lifters and/or had grossly excessive oil consumption in 3 out of 4 AFM engines I’ve owned. I’ve had multiple friends who lost their valve trains at less than 5k miles – before the first oil change was due. No scenario where ANY of these were maintenance or abuse related. When ONE PART of an engine consistently fails, and the rest of the engine shows virtually no wear, that’s not a maintenance issue. AFM/DOD/DFM is a defective concept. Period.
Were those trucks manufactured between 2021 and 2022/2023? Those had defective parts.
While I do sympathize , I strongly suspect there was something behind the failure that may be user caused (aside from the defective parts in 2021 and 2022), regardless of what is mentioned.
Otherwise why were so many of these trucks w/DoD being sold in the Middle East?
08 5.3 – excessive oil consumption beginning at 30k miles – >1 qt per 1k miles
11 5.3 – 1 qt per 1k miles beginning at 180k miles, prior <0.25 qts per 6k miles.
15 5.3 – no issues through 212k miles
16 6.2 – intake lobe/lifter failed at 178k miles, replaced w factory new GM engine, exhaust lobe/lifter failed 123k miles later, disassembled and replaced w DOD delete cam and LS7 lifters. Shop that did work does 2 DOD deletes per week for failed cams/lifter, has 6 week wait to get in.
Referenced friends' Suburbans and Silverados were 20's – 21's.
20 and 21 had defective parts I suspect. 22 as well. It is not like Toyota does not have issues. They have cam tower leaks and valve spring failures that can destroy the engine. And the Tundra is sold in much lower numbers.
Anyways, I see these DoD vehicles being fairly common on Qatar regardless.
I like the LT1 and it’s variants. It’s a great engine and has some tinker capability.
But every 5.0 has forged connecting rods and crank. Ford durability tested them to over 1000hp and Ford will sell you a factory supercharger kit to make ANY 5.0 truck, regular, crew or supercabs, 2wd or 4wd supercharged and 700hp. Only the 8′ box regular cab is excluded.
5.0 is built like a brick crapper house. The LT1 is better naturally aspirated, but the 5.0 eats boost up and it holds up too.
GM won’t even give you a meh it’s ok 5.3 in a regular cab short box. Ford will sell you a 5.0, 10 speed 3.73 truck in rwd or 4wd that makes 400hp and about 430-440hp with e85. No tune. No modifications. GM is run by boring pencil pushers these days.
You are right about the Ford 5.0. It’s a great motor, as are the gm LS/LT engines. Ford’s issue is that they seem to have oiling issues with just about any other motor, unfortunately including the flat plane crank engine in the GT350, turbo 6 engines, and I’ve heard even the GT500 engines are a bit suspect now.
This is interesting, I didn’t know most of that. But those flat plane engines (theirs and now ours) are not as reliable as you’re making them out to be. While I do like and respect them, but hi revving engines just don’t handle longevity as well as the 90° V’s supercharged or turbo, regardless of power adders. Just my $.02
GM is working on updating their V8 engines but I don’t know if they will follow with a turbo 6 or not… honestly I hope not that’s a lot of strain on a turbo engine pulling heavy loads and hauling beds full of stuff, I would rather see a hybrid V8 who knows and by the way Toyota and Dodge hybrids are more powerful but the gas mileage is equivalent or worse then V8 engines… again they are not doing this for customers they are doing it to satisfy the new MPG targets…if you think Dodge and Toyota are doing this for you then you live in a bubble world as well are very full of fantasy in a perfect world they are doing because they are being forced to… otherwise I can’t see Dodge or Toyota giving up tested and reliable engines without an update.

Also I just looked it for the turbo V6 in the Ram it 20/25 MPG and the V8 was 18/23 so it’s a little better but that’s their rating with hauling and towing and what about turbo failure Ford and GM have already experienced this…yes it works with people movers like the traverse and explorer but not a real day to day work truck.
The reason Toyotas 5.7. is so reliable is because it’s been tried and tested before Toyotas racing days it is the reason gm doesn’t offer a 5.7 now. It is the patent off the 350 or 5.7 gm tried and staple work horse. So kudos to Toyota. They improved on an already awesome motor. This is why Chevrolet runs 5.3,then to 6.0 anyway. Way to go toyota
Yet still it had lingering problems such as cam tower leaks.
Hope Ford is offering the optional heated brake lights so you can push em in. The winter months.
I hope GM is reading these comments….. stop being boring GM. Make a fun crossover. Make a XT6-V or at least give it 400hp!. Compete with the Raptor! Make the a Blazer off-road! Bring back the CT6! Make fun commercials like Dodge did! Come on GM.
GM’s justifications are baseless and irrelevant. Why? Because the competition offers what GM won’t.
