Tuner Pushes Ford 7.3L "Godzilla"V8 to 780 HP (Without Boost)
Ford's 7.3-liter “Godzilla” V8 is capable of big power — we know that. Ex-Ford Racing boss Brian Wolfe has been building one for his Mustang Fox-Body drag car and it already impressed with 600 horsepower early in the year. Fast forward a few months and it's still being built, making monstrous output without the aid of a blower, at least for the moment. In Wolfe's most recent test, he was able to push the naturally aspirated pushrod engine over 780 horsepower. Not too bad.
While there's no turbo or supercharger, this Blue Oval power plant is far from stock. Truthfully, it's set up to run a 3.0-liter Whipple, but Wolfe wanted to warm the engine up beforehand so he could deconstruct it and analyze how it performed. As such, it's got a billet intake as well as a 90-millimeter throttle body mounted on top. There's also a good deal of head work; think CNC ported with titanium valves. Still, they're the stock Ford castings, so that's got to be good for something.
Wolfe also notes that it's running the stock block, stock timing chain and stock oil pump. All of these factory parts have supposedly been strong enough to withstand the mountainous pulls they've performed on the dyno with some tests even reaching 7,600 rpm. That might not sound like a lot for smaller, lighter engines but in a 7.3-liter V8, that's impressive.
