As Ramey stated, the 7.3L utilizes an iron block featuring four-bolt main caps with cross bolts in each main, and the block is fully skirted, which adds rigidity. Bore and stroke comes in at
4.22-inches x 3.976-inches, respectively, to produce 445 cubic inches of displacement........
Unlike the 4.6L Two-, Three- and Four-Valve modular and DOHC 5.0 Coyote engines, this is a big incher in a relatively small package. We don’t have specs yet, but it appears to be no larger than a typical small-block Ford. And with engine swaps being all the rage, it will only be a matter of time before we see one in a classic Ford, late-model Mustang, a street rod or dare we say, in a GM product.
Of course, there will be obstacles, and one we see is the extra-deep oil pan. Normally, this wouldn’t present an issue, but the integrated oil pump and pick-up may present a challenge if you plan to set the engine in a low car. The off-road market would simply eat this thing up, especially the classic truck crowd.
