The refreshed 2022 GMC Sierra 1500 officially made splashdown in October of the 2021 calendar year, introducing a wide variety of changes and updates for the light-duty pickup nameplate. Now, GM Authority has learned that the 2022 GMC Sierra 1500 is currently unavailable to order with the naturally aspirated 6.2L V8 L87 gasoline engine.
According to GM Authority sources, production of the 2022 GMC Sierra 1500 has been impacted by unavailability of the 6.2L V8 L87 engine. The engine is scheduled to return to 2022 GMC Sierra 1500 production on July 18th, 2022.
Customers waiting for their pickup to be built with the 6.2L V8 L87 engine will likely be contacted by their local dealership with alternative solutions. These include delaying production of their new pickup truck, or selecting another engine option, if available.
As a reminder, the 2022 GMC Sierra 1500 is available with four engine options. In addition to the naturally aspirated 6.2L V8 L87, which is rated at 420 horsepower at 5,600 rpm and 460 pound-feet of torque at 4,100 rpm, the 2022 GMC Sierra 1500 can also be had with the naturally aspirated 5.3L V8 L84 gasoline engine, rated at 355 horsepower at 5,600 rpm and 383 pound-feet of torque at 4,100 rpm, the turbocharged 2.7L I4 L3B gasoline engine, rated at 310 horsepower at 5,600 rpm and 430 pound-feet of torque at 3,000 rpm, and the 3.0L I6 LM2 turbodiesel Duramax, which is rated at 277 horsepower at 3,750 rpm and 460 pound-feet of torque at 1,500 rpm.
Notably, the fully refreshed 2022 Chevy Silverado 1500 is also unavailable to order with the naturally aspirated 6.2L V8 L87 gasoline engine, as GM Authority covered previously. Under the body panels, the 2022 GMC Sierra 1500 rides on the GM T1 platform. Production takes place at the GM Fort Wayne plant in Indiana, as well as the GM Silao plant in Mexico.

They have the 5.5 dohc, they need to put that to premium truck duty pronto ..
I’d rather have the 5.3 than the 5.5. It’s OVH and not DOHC. That makes it smaller and lighter, and more powerful under 4000 rpm’s.
Most NA engines build their peak torque by tuning the ports and intake runners so that the air rushing through the ports has enough inertia to “stuff” the chamber. Using inertia as a means of building “boost” pressure. The smaller the ports, the lower this phenomenon occurres. Small blocks with 2 valves have a more restrictive airway that has loads of flow. For example.
L86 (6.2) max torque at 4100 rpms
L8T (6.2 stroked out to 6.6l, but same heads) max torque at 4000rpms
8.1 vortec (stroked 7.4, and intentionally restrictive heads with an obnoxiously long runner plenum) max torque at a diesel like 3400 rpm.
The 5.5 with 2 intake valves doesn’t experience that effect till after 6000 rpms, with max torque at 6700.
Unless you intend to cruise at 4000 rpms, or tow at 7-8, the 5.5 is not ideal. If you want to pass, you will need to downshift from a cruising 1200 rpms all the way up to 5000 before beginning to build top torque.

As said it should be a premium truck only motor tuned to around 500hp instead of the race-ready 670 in the Vette nor strictly for hauling construction materials or HD truck stuff
Re-read what I’d typed, I’d said premium engine not a 6.2 replacement
As said it should be a premium truck only motor tuned to around 500hp instead of the race-ready 670 in the Vette nor strictly for hauling construction materials or HD truck stuff.
So the LT2??? You do know the 5.5 makes less torque than the 6.2 right? (In corvette applications the 6.2 makes 465 tq. Long exhaust with back pressure) DOHC engines don’t make their torque till past 4000 rpms. OHV start their torque at 2500 rpm and go from there.
Think ford coyote vs a small block. The coyote V8 is a very weasy engine. Ford made the coyote for fuel economy reasons as they could manipulate all 4 camshafts. They didn’t want to go the cylinder deactivation route and admit Chevy knows how to build a better truck V8.
So it needs to be tuned make more, all this “it’s heavier” if it’s in a truck that won’t matter, also it can’t be that heavy as it’s in a Vette, plus this article is about limited 6.2 production so there goes the simple production argument..
While I’m at it want me to tune the 4.3 to make more torque than the 6.2? That’s my whole point. The 5.5 doesn’t have the displacement to replace the already smaller and lighter physically 6.2 small block. What you want as a premium engine would be the LT2 or an LT version of the L8T, probably called the LT8.
This brings back up the reason d’etre of the LT6. One of the main reasons it exists is not because it’s more powerful than the LT4 it’s replacing. If that was all GM could easily dropped in the LT5 with its 750 ponies and blow everyone out of the water. The Z06 is a race car. Many races dominated by brands like Ferrari and Porsche are tired of being beaten by huge American V8’s and have a displacement limit of 5.5L, and don’t allow for superchargers. The LT6 exists because of race limitations, not because it’s better.
As said the 5.5 is not for the log hauling crowd, as with Ford has it’s EBs for it’s premium trucks and STA has it’s 3.0tt, those engines didn’t replace the v8s. The 6.6 can’t meet emissions in LD trucks is why it’s not available in LD trucks, you can say “lighter” all you want it doesn’t make a difference in a 6000 lb truck, the point is it’s still more powerful in hp then the 6.2 and probably does it while running smoothly.
The 5.5 *could be* tuned to produce significantly more torque than a 5.3, at even lower RPM than the 5.3. It could also be tuned to produce more torque than a 6.2 at comparable RPM. Less camshaft duration and looong intake runners. Would be bedazz. They won’t do it.
The 5.5 is great and all. But displacement matters in a TQ application. The short stroke just doesn’t work.
I would love to see a “modular” approach to GM’s V8’s. 5.5 short deck flat plane and a tall deck cross plane with a larger swing. 4v a cylinder and gobs of power now that the bore spacing isn’t choked like Ford’s was back in the day. Valve shrouding is real.
That’s what I mean by turning it for truck duty. The 5.5 as is won’t cut it, a lower output and changes to it’s intake, program, certain other parts would make it idea IMO.
You still are pitting a DOHC against an OVH engine. DOHC’s are much larger and heavier, and you only see the advantage past 5000rpm’s. Ford who has their known rugged modular SOHC engines designed the new godzilla V8 a pushrod for this very reason. Unless you intend to run the engine at high rpm’s the advantage is for the OHV pushrod every time. It’s smaller, lighter and has way less friction as it doesn’t have 4 cams and 3 timing chains. DHOC’s don’t even make that much more power unless you decide to go with a flat plane crank screamer. Look how the LT2 compares to the ford coyote. The LT2 is also lighter and cheaper to produce than the coyote. Instead of designing a high reving DOHC, they would be way better off taking the L8T and increasing the compression ratio and fuel maps.
Is the “no 6.2” situation unique to trucks, or is it applicable to SUV’s, as well? If so, the Escalade and Denali market just changed significantly.
GM is a joke. Reserved the 2022 Denali Ultimate October 2021 paid the local dealer a $1,000 deposit in January and still no word on a production build date. If I can’t get the 6.2 engine will I have to wait for the 2023 model? If so I’m done with GM as my second choice was to go with the Chevy High Country Silverado that is not providing the 6.2 engine either. The upcoming 2023 Ford Raptor R is looking better to me everyday. Ram is out the question I don’t want a 12” vertical mounted iPad on the dash.
It’s nice watching wealthy people like you stuck in Limbo.
Just got a call today, from my dealership, that I ordered an At4X through, they notified me, as of right now, there are no more 6.2 liter V8’s, but according to GM, I could choose the 5.3 liter V8 or the diesel. They were just told this from GM, and were not given a reason for the cancelation of the 6.2 liter motor. My trucks been on order since the beginning of March, reserved one the moment you could back in 2021, now GM is pulling this crap. Super disappointed, considering getting my reservation, $100, back, and ordering a 2023 35″ package Raptor in August, basically the same price! LETS GO BRANDON!!!
No diesel offered in the AT4X is what has kept me on the sidelines. You’re saying they’re offering you the 3.0 diesel as an option now, in lieu of the 6.2, in the AT4 “X”??? That’s a big deal. But we’ve also read the diesel is on hold in most higher-end trims. Yes, Brandon has gotta go.
So you reserved back in November but didn’t bother to actually order until March….even though it’s so important for you to get the 6.2.
Now, you want to blame this all on the POTUS because he manages production for US companies? Reality is, you snoozed and now will have to wait even longer. LETS GO JASON!!! The stupidity going around this country is ridiculous.
Bill Maher had a great new rules segment 3 days ago: The United States of Dumb-Merica.
Highly recommend watching it and take note of how your average Joe thinks Queen Elizabeth is from Egypt.
Interesting, I just custom ordered the ZR2 a few weeks before the “6.2l Silverado is unval to order” article published. Talked to my dealer yesterday. “All orders, accepted by GM have 6.2l motors available, your order is in production now” You can still order AT4X, ZR2 and HighCountries with the 6.2L, just as you can order a 6.2L Tahoe. Something doesn’t seem right with your story.
I would have ordered the AT4x if I knew GM was going to let me get a diesel with it.
Delay due to ocean carrier conjestion at the ports and supply chain ocean carrier freight bookings. The 6.2’s made by VinFast in Viet Nam are in ocean transit awaiting off loading at Long Beach and transfer to GM assembly plants. The River Road Engine assembly plant in Tonawanda, New York is being tasked with other models of IC engine assembly. Eventually River Road will be phased out, when all electrics come in.
GM is smart to contract with VinFast at this point for big IC engine production. Mechanical automatic transmissions are being contracted out to Tremec in Mexico, as mechanical automatic transmissions will also be phased out when the electrics come in.
The GM drive train plant next to the Parma metals stamping plant in Cleveland, Ohio has been closed up for several years.
Forward planning my friends for the future electric world.
Where are you getting that a five year-old company in Viet Nam is now making 6.2 V8’s for GM??? They’ve bought some 6.2’s from GM to put in a few hundred of their SUV’s, but they’re supposed to go 100% electric by the end of this year. I don’t see them casting much of anything.

On the VinFast website. VinFast is the largest manufacturing conglomerate in Viet Nam. They make shiploads of car parts for OEM’s. Well financed. VinFast is also going to build a plant and make electric vehicles in North Carolina soon. Their EV pricing will be down and dirty to capture market share.
The Vietnamese are a savvy people. They held the America forces at Bay for many years and finally beat the the pants off the Americans forcing the Americans to exit and declare victory for themselves. Now they are rocking and rolling. Quality products at affordable prices. Will the last persons leaving Detroit please turn out the lights.
Okay, you say their website says they make “shiploads of car parts for OEM’s.” We know they bought the old GM plant in Viet Nam, and they are the exclusive distributor of Chevrolets in Viet Nam. But show me ANYTHING that says they manufacture 6.2’s for GM and ship them to the US.

Lots of job shop foundries in the Orient. They are not strangled with OSHA and EPA regulations.
Caterpillar has moved most of their castings from Mapleton, Illinois to a large private foundry in Mexico.
Cummins has never made any of their castings, nor do they want to. Let a vendor handle this dirty, risky business. Lots of worker comp claims with foundries and the worker compensation insurance rates for foundries are insane. That’s why most of the foundries have closed in the upper Midwest heartland. Will the last persons leaving Cleveland, Ohio, please turn out the lights.
The Chinese are now huge into gray iron castings for US manufacturers.
I’m intimately (and painfully) familiar with the transition of manufacturing from the US to Asia. But the fact that Caterpillar did this and Cummins did that doesn’t support your assertion that the reason 6.2’s are on hold is because they’re sitting on a ship enroute from Viet Nam.
Again…Show me something that say VinFast manufactures 6.2’s for GM and ships them to the US.

Go to the VinFast website. Drill into it. VinFast states they make 6.2’s for GM. Specifically the Corvette 6.2. Check it out. Reply back to me if you can’t find it. Too bad that we cannot post links or screen shots on this site.
I see long wait times if at all for parts in the future. Cottage industry suppliers.
