There is an age-old adage in the world of automobiles that once defined performance: there is no replacement for displacement. While this way of thinking has fallen by the wayside in this age of downsizing and forced induction, sometimes old wisdom is still applicable today. Ford was one of the pioneers of shoving smaller boosted engines inside of a half-ton truck, but that hasn’t stopped them from building the all-new and magnificent 7.3L Godzilla V8 engine.
This massive chunk of metal was designed for the latest iteration of the Super Duty truck line, as Ford says that the lazy V8 is more efficient in high-load towing situations than the smaller engines in the line-up. While the new pushrod eight-cylinder marks an improvement in efficiency, it is also the largest displacement engine available in a truck today. With a power output of 430 horsepower and 475 lb-ft of torque, it’s fairly powerful for a naturally aspirated truck motor as well.
That is exactly why it hasn’t taken long for hot-rodders to tear into the Godzilla V8 engine and start to play around with it. REVan Evan is a YouTuber who recently headed over to Michigan-based Team Z Motorsports to get some insight as to what these motors are really capable of. With the former head of Ford Performance Brian Wolfe at the helm, Team Z Motorsports and REVan Evan have made a five-part series on the 7.3L motor.
While all five of the videos offer up interesting information about the 446 cubic-inch Godzilla V8, it is the fifth video that features a number of dyno runs that is truly impressive. With only a few basic mods, including a ported intake and exhaust, a custom intake manifold and a high-lift camshaft, the Godzilla V8 produces 588 horsepower and 508 lb-ft of torque.
As if a nearly 600 horsepower naturally-aspirated V8 isn’t cool enough, this particular pushrod V8 will fit in the foxbody Mustang. In fact, Team Z Motorsports is in the process of doing just that. Ford Performance has a catalogue of crate engines available for order, but the Godzilla V8 is not on the list at this time. Sure it might be heavier than the Coyote or a Windsor 351, but getting either of those motors to 600 horsepower without forced induction is an immense challenge.
Ford, let the people have what they want.
