Ford's fabled 7.3-liter "Godzilla" V8 engine has proven to be capable of producing higher levels of power than anyone ever imagined. The V8 pushrod engine is offered in the Ford F-Series Super Duty pickup trucks, where it produces 430 horsepower and 475 lb-ft of torque.
Now that Ford offers it as a crate engine, Godzilla has been used to power some unique restomod projects. Thanks to some modifications, former Ford Racing director Brian Wolfe managed to extract 789 hp from the V8 pushrod for his Fox-Body Mustang drag car project without resorting to forced induction.
