Tuner Gives Ford's Godzilla An 800-HP Lease On Life

Tuning / Comments

It's going to be powering a Fox-Body Mustang drag racer.

Debuting on the F-Series Super Duty, Ford's new 7.3-liter "Godzilla" pushrod V8 is already capable of producing 430 hp and 475 lb-ft, but it didn't take long for Brian Wolfe, the former Director of Ford Racing, to extract more power from this new unit.

Earlier this year, Wolfe got to work transplanting the new 7.3-liter V8 into a Fox-Body Mustang to turn it into a drag racer. Back then, Wolfe's modifications, which included upgraded cylinder heads, a reworked intake, and a higher lift camshaft, raised the output to an impressive 600 hp. A few months later, Wolfe has made significant progress on the project.

In this latest video posted by YouTube channel REVan Evan, the pushrod V8 produced 789 horsepower at 7,600 RPM when it was hooked up to a dyno. That's insane considering there's no turbo or supercharger, although the powerplant clearly isn't stock.

As Wolfe explains, there's a billet intake installed along with a 90-millimeter throttle body from a Mustang Shelby GT350 mounted on top. There's also an upgraded Westcott mechanical roller cam, Wiseco pistons and MGP aluminum connecting rods.

The cylinder heads still have stock Ford castings and it's also still running the stock block, stock timing chain, and stock oil pump, which were able to withstand the monumental levels of power. The engine has been set up to be fitted with a 3.0-liter Whipple blower, but Wolfe wanted to see how it performed without one.

Unsurprisingly, this level of power isn't achievable with regular pump gas. Instead, the unit used for testing ran on VP Racing Fuel's C16 blend. Wolfe is even confident the naturally aspirated V8 could achieve over 900 hp with the right setup and 1,550-1,650 hp with the supercharger installed to make the car competitive on the drag strip. We can't wait to see the finished project.
