Modded Ford 7.3L Godzilla V8 Makes 780 Horsepower On The Dyno: Video

There’s been quite a bit of excitement surrounding Ford’s 7.3L Godzilla V8 since the new gas-powered engine was revealed. Since then, we’ve seen the big pushrod motor shoved in a Fox Body Ford Mustang, offered as a standalone crate motor, and get a major power boost from Whipple’s new supercharger kit. Now, a somewhat mildly modded Ford 7.3L Godzilla V8 has laid down some seriously impressive numbers on the dyno.

This particular modded Ford 7.3L Godzilla V8 has been in the works for a little while now as its builder, retired director of Ford Racing Brian Wolfe, prepares it for NMCA eighth-mile drag racing. Wolfe’s goal is to get around 1,600 horsepower out of the stout motor, but for now, he’s working on testing the current modifications before he slaps a giant supercharger on it.

As one might imagine, the 7.3 is not stock by any means, but it is running the original block and heads. Otherwise, the mods consist of a giant custom billet intake, lifters, a mechanical roller cam, 90mm throttle body, and aluminum pistons and rods. Compression comes in a 12.5:1, and the engine has also been treated to titanium valves, push rods, and a beefier rocker system.

Regardless, the results of this dyno test are nothing less than mind-blowing, as the modded Ford 7.3L Godzilla mill lays down a ridiculous 789 horsepower and 558 pound-feet of torque. Given the relatively mild list of mods and lack of forced induction, that’s quite impressive. Even better, Wolfe believes that it’s capable of hitting 900 horsepower, naturally-aspirated, with the stock head castings.

That’s an absolutely astounding figure for any N/A engine, let alone one that’s mildly modified and quite capable of street duty. Wolfe says that he’ll have the 3.0L Whipple supercharger on the motor in a few weeks, and we don’t doubt for a second that he’ll eventually get to that 1,600 horsepower goal.

Brett's lost track of all the Fords he's owned over the years and how much he's spent modifying them, but his current money pits include an S550 Mustang and 13th gen F-150.

    Its about time some one started playing with the Ford power and stopped following the herd with Chevy

    The torque number says those cylinder heads must be terrible. I have a 10:1 400 SBC (6.6L) with fairly small 224/224 hydraulic roller and AFR heads that makes 540 lb ft at 4100 RPM.

      You must have defective parts. I have the same setup and it makes a billion torks at -1 rpm
