It will be based on the overhead-valve 7.3L "Godzilla" V8.
For many American muscle enthusiasts, it was a dream-come-true when news broke that Ford would sell its torquey, 7.3L "Godzilla" pushrod V8 as a crate engine. The mill might have gotten its start in Ford's F-Series Super Duty trucks, but since its introduction, the interest from the classic muscle car tuner crowd has been palpable.
Already, though, Ford is working on the next big thing in large-displacement overhead-valve crate engines: a more powerful version dubbed "Megazilla". News of that motor's existence was shared by Ford Performance Product Manager Mike Goodwin in a video walkthrough of the Godzilla crate engine package, published by Performance Racing Industry last month.
Here's what we know: nothing. Nada. Zilch. Goodwin referred to the engine as a "super-secret project," and Ford appears ready to keep it that way for the time being. But from the sounds of it, the "Megazilla" V8 will be an up-tuned version of the 7.3L Godzilla, likely sharing its block and its displacement, but boosting its performance through other means. Freer-breathing cylinder heads, alternate cam profiles, alternate pistons pistons, long-tube headers, a higher-flow intake plenum - in theory, Ford could use some or all of these things to increase performance in the 446-cubic-inch V8.
Bear in mind: one tuner has already managed to extract a mind-blowing 789 naturally aspirated horsepower out of the 7.3L Godzilla at 7,600 rpm, with mods including a 90 mm throttle body, billet intake, modified heads, and mechanical roller cams, so the engine has plenty of overhead built in.
Not that there's anything wrong with the stock 430 horsepower, and from the overview, the Godzilla crate engine sounds like an excellent platform for any muscle car build. Goodwin describes the factory ECU tuning as a "starting point" for tuners to modify as they introduce additional performance parts like headers and cams, and he says there's even a package on the way aimed at manual transmission compatibility, for those who just can't bring themselves to embrace Ford's ten-speed auto.
So what sort of vehicles is the Godzilla crate engine aimed at? Basically anything that can fit it. Goodwin suggests it will pair nicely with a Fox-body Mustang, a classic F-100 pickup, an old Bronco, or "heck, you could even put it in a shopping cart and make it run," he says.
But remember, folks: safety first. You should always, always brace and seam-weld your shopping cart if you're going to substantially increase its power output.
