With 430 horsepower and 475 lb-ft of torque coming on at just 4,000 rpm, we all had a sneaking suspicion there was more curve on tap. Ex-Ford Racing boss, Brian Wolfe, proved it by running a lightly modded version of the 7.3 to 600 hp and then later, to 780 hp.
Well, Mr.Wolfe is back at it again, this time with a built-up, supercharged version of the Ford Godzilla V8 engine that kicks out 1,450 horsepower at like 7,800 rpm.
Wolfe and Willis Performance Enterprises assembled the “new” 7.3L Godzilla V8. It got house-made “stage three” heads with WPE shaft-mounted rockers, Jesel mechanical roller rocker arms, and Jesel keyed lifters. Plus there’s a Charlie Westcott Jr. mechanical roller camshaft, Weisco forged pistons, and MGP Rods.
The rotating assembly still spins on the forged factory crank inside the factory block, but it did get a Dailey dry-sump lubrication system, and it’s managed by an OBR ECU which fires the stock ignition coils.
The real jam though happens thanks to a 3.0L Whipple Supercharger blowing 16.6 psi of boost courtesy of a low-key-party pully, and a bellmouth for max inlet velocity. The result is a billiard smooth torque curve that carries more than 1,000 lb-ft of twist all the way past 7,000 rpm.
Because Wolfe plans to drop this motor into a Foxbody drag car he’s been building, the big dyno figures were produced using VP Racing C16 race gas. Still, the potential from Ford’s new OHV design is even more exciting when you look forward to the upcoming, scaled-down, 6.8-liter version of the Godzilla V8 that’s been rumored.
Regardless of what happens on the OEM side, Wolfe and Willis Performance Enterprises are certainly pacing the field when it comes to hot-rodding Ford’s newest V8. At least until Ford Performance gets around to dropping the “Megazilla” version of the 7.3L…
