Ford Megazilla 7.3L Crate Engine Officially Revealed

The naturally-aspirated Ford 7.3L V8 Godzilla originally debuted in the 2020 Ford Super Duty, but was soon offered in crate motor form as well, and has since proven to be a popular option among those looking for a turnkey engine with excellent power potential. This past July, Ford Performance added an entire Godzilla powertrain package to its catalog that includes everything one needs to swap the engine into all sorts of other types of vehicles, too. However, we’ve known for some time that a more powerful version of the Godzilla was in the works, particularly after FoMoCo filed to trademark “Megazilla” back in September. Now, the new Ford Megazilla crate engine has been revealed.

The new Ford Megazilla powerplant was unveiled at the recent 2022 Performance Racing Industry (PRI) Show in Indianapolis, Indiana, and as expected, it’s a beefier version of the existing 7.3L Godzilla, though both feature natural aspiration and the same exact displacement, cast iron block, and forged steel crankshaft.

However, the two differ in a number of other ways, as the Ford Megazilla utilizes beefier internals including Callies forged H-beam connecting rods, forged Mahle pistons, a VCT delete, a 92mm throttle body taken from the Ford Mustang Shelby GT500, and Ford Performance’s low-profile intake manifold and CNC-machined cylinder heads, while the revised V8 touts a 10.5:1 compression ratio. The result is a big boost in output, from the Godzilla’s ratings of 430 horsepower and 475 pound-feet of torque to 615 horsepower and 640 pound-feet of torque.

What’s particularly notable about the Megazilla’s output, however, is where that power is available. Horsepower peaks at 5,800 rpm, but torque remains above 500 pound-feet from 2,500-6,000 rpm, giving it plenty of low-end grunt, while the full 640 pound-feet arrives at 3,800 rpm. Ford hasn’t yet announced how much the Megazilla V8 will cost, but the Godzilla crate engine currently features an MSRP of just over $9k. The updated powerplant is scheduled to launch in Q2 of 2023, giving builders a new, compelling choice in terms of brand new, turnkey engine options.

    GM’s ZZ632/1000 is dead sexy, especially those cylinder heads. It’s not the so much the 100 hp/l the big 10 liter puts out. It’s the fact that it’s a 2-valve engine running 12:1 on pump gas and generates a BMEP well over 200 psi putting it up there with engines from Porsche and Ferrari and it does this on a huge four and a half in bore with two valves, one cam and a fast burn chamber without a centrally located plug (its close but doesn’t sit in the center like a pent roof head) and without the benefit of direct injection. Plus, it’s a damn good-looking engine.

    Megazilla/Godzilla might not be as sexy, but it is a solid engine, better yet, it gives Ford guys a nice alternative to the physically larger Coyote V8 engine since it is about the size and weight of a 351 Cleveland, so it fits in a lot of older Ford chassis without the sort of modifications required to fit a Coyote (like cutting and relocating the master cylinder mounting boss on the firewall on 1st gen Mustangs or swapping in hydroboost on later model Mustangs to clear the cam covers which makes the swap easier and cheaper). The icing on the cake is it’s another stab in the heart of the “LS Swap The World” goon squad.

    I’m still waiting for some fool to cram a 7.3L into a Maverick.

    While I have a 521 BBF in my Lincoln MkV, this would be sweet with an overdrive trans.

    It’s Nov 13, 2023. Anybody seen the 615hp Megazilla 7.3 L crate engine? I just checked, only the 430hp Godzilla 7.3 L listed. Has the Megazilla 7.3 L gone extinct on the way to market? There has been silence on the subject since Dec, 2022.

    11/30/23: A Chat Tech at .com told me the Megazilla 7.3L might be available December, ’23 or January, ’24, with a price tag in the $21,000 neighborhood. (Scratch “affordable” out of the product description) There us no info on a engine/ transmission combo package.
