Ford 7.3L OHV 2-valve V8 specs: 445 ci (7.3L) 8-cylinder, 4.221 x 3.976 in (107.2 x 101 mm) bore and stroke. Rated 430 hp, 2020–2026.
The Ford 7.3L OHV 2-valve V8 is oversquare — the 4.2205" bore exceeds the 3.9764" stroke by 6.1% — a layout that favors airflow and RPM over leverage at the crank. The 3.9764" stroke puts mean piston speed at 4,000 ft/min around 6,050 RPM, which is where a production bottom end is generally considered at its limit. Each of the 8 cylinders displaces 55.6 ci (912 cc).
It is one of 2 engines in the Godzilla family, all of them 445 ci — the differences between them are in compression, heads and rating, not displacement. 7 factory variants share these dimensions, rated at 430 hp across 2020–2026.
