Ford is reportedly working on a twin-turbocharged version of its Godzilla V8 engine that it currently offers in the F-Series Super Duty line of trucks.
The Godzilla V8, which is also available as a crate motor, is a naturally aspirated, pushrod V8 engine with a whopping 7.3L of displacement. The engine was introduced to the F-Series Super Duty lineup as an indirect replacement for the automaker’s 6.8L Modular V10 engine and is rated at 430 horsepower and 475 pound-feet of torque in its highest state of tune.

According to our sister site Ford Authority, the Blue Oval is now experimenting with a twin-turbo forced induction setup for the Godzilla V8 engine. Very little is known about this new twin-turbo V8, but Ford Authority’s sources say the boosted eight-cylinder is being tested in at least two different Ford Super Duty test prototypes and describe the engine as a verifiable “monster.” The sources also say these prototype trucks can be easily identified as they have unique heat shields on each corner of the front end, along with a modified hood treatment, although photographers have yet to catch them out in public.
As stated above, the 7.3L Godzilla V8 produces 430 horsepower and 475-pound-feet of torque in certain F-Series Super Duty models, though less powerful and more eco-friendly versions of the heavy-duty engine are also available in the E-Series cutaway and F-600, as well as the F-650 and F-750 heavy trucks. It’s safe to say the twin-turbo version of the engine would have over 430 horsepower, but it’s not clear how much more power it may produce, or what kind of vehicle application it may be used in. GM should keep its eyes peeled for more information on this front, though, as this Ford-built pushrod engine has the ability to steal some of the thunder from its own push rod Small Block V8s like the 6.2L L87, for example.
We’ll keep a close eye on this story as (or if) more information comes to light, so be sure to subscribe to GM Authority for more GM-related Ford news and ongoing GM news coverage.

Naturally Aspirated , SuperChargered, or Twin Turbo aka EcoBoost Godzilla 7.3 is shaping up to be a great power plant. It would be a major mistake not to bring this motor to market in the Super Duty and as a crate offering for customers
I am with Jake on this one with gas prices going up and a bigger engine coming that means that people with deep pockets are going to be the ones buying this big engine. Bigger motor means more gas used to fire each cylinder. Yeah I love the idea of this engine coming out and all but who is going to buy a truck with this engine well I can tell you it is not going to be me or not until I hit the lottery I guess. But like I said bigger motor means more gas and more gas used is more money to fill up that massive tank they are going to install into this motor.
There is a rumor about an 8l “small block” coming from GM. I wonder if any of these come to fruition.
If GM builds a new small block with 8 liters, it will only be used in trucks that need maximum torque, such as the Medium Duty 4500, 5500 and 6500 models. Possibly as well in the HD pickup with the 3500 model and dual real wheels. Here’s the math on it’s insides, if the existing HD pickup block is used. The 6.6 liter gasser needs to have a long stroke of 4.25 inch or 107.95 mm and a bore of 4.15 inch or 105.41 mm, to give the 8 liter new big cube engine.
The reason to use the 6.6 gas engine as the base is because it has small water jackets on all sides ( drilled between cylinders ) and cam phasing and other trick stuff that the latest GM engine has, rather than the new (2009 ) unused 8.0 liter big block, that was never installed in a production vehicle. It doesn’t have cam phasing or cylinder deactivation. The big block (2009 new design) 8.0 liter has full water jackets, but the LSX 454 small block does not have full water jackets and this means it will overheat when pulling a 14,000 pound trailer. Remember that the L8T 6.6 engine has better technology than the old tech LS and LSX blocks. Parts sharing between the 6.6 L8T and the bigger 8. liter version of it, can be shared and so can any future development work. GM can even do the same thing they did with the original 350 V8 to make a V6 engine by developing a 4.3 liter V6 version of the L8T V8. GM sells those 4.3 engines as industrial engines and a huge number of them are sold as boat engines for many companies. Or they could develop a V4 off the bigger 8 liter L8T base design and get a large 4 liter or 243.6 cubic inch. This will be a perfect big 4 cylinder for the Chev Colorado to compete with the Toyota small pickup truck. If GM put a turbo on that 4 liter V4, it could be used a a high performance version or SS or Redline in the Colorado. Image that turbo V4 in a boat, lots of torque for towing skiers but much more economical that a V6. The turbo V4 of 4 liters would be about 385 pounds feet of torque or a bit over 400 if it was set up as a SS or Redline version.
The current Colorado engine line competes rather well with the Tacoma, as to the next gen Colorado/Canyon, GM already said the vehicle will offer the 2.7L Turbo I4, that engine fits the segment nicely.
But it’s not electric?! Thanks.
This engine could perfectly fit in a new Excursion ! Along with a V8 Diesel.
Who in this world and in his right mind would want or need that engine in an Excursion? Com on.
Well, first of all those who are interested in a new Ford Excursion ! Those with an Excursion who must tow heavy loads, but prefer an SUV rather than a pickup. Probably not millions of people but enough to make it a business plan.
On a serious note. What is the use of this motor? Crate engine? Commercial HD? This motor would be more powerful than the powerstrokes, but would suck gas. TFLTrucks mpg comparison of the 7.3 vs the 6.6 retured the taller Chevy with the humble 6 speed on top empty and loaded in flat country. The two were equal in uphill tow drag racing. This thing would suck gas worse than a LT4. Course Cadillac seams to be putting an LT4 in the Escalade. As powerful as the 7.3 is, it’s a guzzler.
Come on Jake, have some fun once in a while. Some of us don’t fit, nor do we like the small cars like Corvettes, Mustangs, or the European “supercars”. Is there any reason why WE can’t have a full-size pick up or SUV with mega power? More power makes it easier to pull heavy loads, more power also means that the engine isn’t working as hard, thus making it longer lasting. No reason small skinny people only get to enjoy vehicles with some getup and go.
People who want performance pickups already buy the diesel.
Good luck and getting any real power out of a diesel and maintaining a fully functioning emissions system to keep it smog legal.
Lol the Ford 7.3 absolutely murdered the GM 6.6 by 3 minutes in the Ike. They weren’t even close dude. The 6.6 was to the floor and the 7.3 was laughing.
Production TT big block?,unless it’s going into
something commercial it’s the perfect small Enos enhancement….
Let’s not be fooled by the supposed thirst of this new engine. Recent engines have much better economy ratings. Start & stop, cylinder deactivation, better transmissions… Hybridation… Also, Ford seems to embrace aluminium body techniques that make everything lighter. At the end of the day, people are supposed to know what they pay for, and why.
