In the latest installment of auto journalist and racer Evan Smith’s exploration of Ford’s new monster 7.3L Godzilla engine which will power the 2020 Ford F-250 Super Duty pickup, Smith weighs the engine and unleashes it on the dyno for sound.

Dressed with aluminum cylinder heads and a composite factory intake manifold, the robust iron block 7.3L weighs 538 pounds.

For comparison, a 428 cubic-inch Ford 351 Windsor iron block engine that Smith weighed came in at 471 lbs., and a 302 c.i.d. dual-overhead cam Coyote engine weighed 404 lbs.

“That’s a pretty big difference in weight. A 134-pound swing,” Smith said. “But the 7.3L motor makes it up with cubic inches and hopefully with cylinder heads.”

Smith shared that he’s hearing rumors of aftermarket companies already working on performance cylinder heads for the new 7.3L engine.
