Ford's Mammoth 'Godzilla' V8 Isn't Coming To The Mustang

But there's nothing stopping you from swapping it into your project car.

"There's no replacement for displacement," or so the classic expression goes. Ford might have taken that advice to heart in designing its mammoth, 7.3-liter "Godzilla" V8 - an iron-block pushrod V8 that represents the largest-displacement internal combustion engine currently in a production vehicle. An output-obsessed performance car enthusiast could do a lot with an engine like that; Whipple has even released a 3.0L supercharger kit for it, which is about 300 cubic centimeters bigger than the blower on the 808-horsepower 2018 Dodge Challenger SRT Demon.

But unfortunately, Ford has no intention of putting its big honking pushrod V8 in a performance-oriented vehicle, Ford Mustang or no. No factory "Boss 445" in this lifetime.

"I'm not aware of any plans for [Mustang]," Pat Hertrich, the engineering supervisor on the Godzilla project, told Muscle Cars and Trucks recently. "This is a truck engine for commercial use."

That's not to say that Hertrich isn't a fan of some of the engine swaps performance enthusiasts are carrying out. "When you're putting out a gas engine this big, you kind of know that's going to happen," he said. "Anybody who is into muscle cars and drag racing will start immediately thinking big blocks and big power."

"As an engine person, to me, that's very exciting," he added.

Nonetheless, Ford's Godzilla V8 was built with just a singular purpose in mind: to work. It's a unique design, not based on any other V8 in the Ford production V8 lineup, available in the 2020-model-year Ford F-Series Super Duty and Ford E-Series vans. Peak output is a stout 430 horsepower and 475 lb-ft of torque.

Granted, it's already been proven that the Godzilla V8 has plenty of overhead for tuners; just this month, Brian Wolfe, Ford Racing's former director, managed to squeeze nearly 800 horsepower out of the mill while keeping it naturally aspirated. The engine will eventually power a Fox-body Mustang drag racer.

With a retail price of just $8,150, we imagine the engine will land in plenty more drag racer projects before production is through.
