The Power Stroke is an electronically controlled, direct injection engine with a 4.11 in × 4.18 in (104.4 mm × 106.2 mm) bore and stroke creating a displacement of 444 cu in (7.3 L).

The International Harvester Company (IHC) has been building its own proprietary truck engines since the introduction of their first truck in 1907. International tended to use proprietary diesel engines.

All gears are synchronized. There is a dual cone synchronizer on 2nd and 3rd gears with an input torque rating of 520 ft-lb.
At their launch, the F-650 and F-750 were available with the Caterpillar 3126 (replaced by the C7) 7.2L inline-six, the Cummins ISB 5.9L inline-six, and the Navistar-produced Ford-branded 7.3L Power Stroke V8 engine.
