In a still-heated market for highly profitable heavy-duty pickups and commercial vehicles, Ford doesn't intend to be outdone by General Motors' and FiatChrysler's recently-launched new efforts, announcing the power and torque figures for its all-new 7.3-L gasoline V8 for its 2020 models and reminding that major revisions for 2020 for its Power Stroke diesel V8 also portend to increased power.

At a late-July media event, Ford revealed that the new 7.3-L, which revives the overhead-valve layout Ford largely abandoned years ago for gasoline engines, generates 430 hp at 5500 rpm and 475 lb-ft (644 Nm) at 4000 rpm. The figures conveniently slip past the 401 hp and 464 lb-ft (629 Nm) available from GM's 6.6-L gasoline V8 and the 410 hp and 429 lb-ft (582 Nm) FCA deals out with its 6.4-L Hemi V8-both of which, it may be no coincidence, also are OHV designs.
