Ford has announced
the preliminary details of the new 7.3-liter V8 engine, which will debut in the
F-250 and F350 as an option, and will eventually become standard in the F-550,
F-600, F-650, F-750, F-53, F-59 and E-Series.
The Windsor-built
gasoline unit features overhead valve architecture that helps it generate power
low in the rev range, variable-displacement oil pump, piston cooling jets,
extra-large main bearings and a forged steel crankshaft.
With 7.3 liters in
displacement, the V8 delivers 430 hp at 5,500 rpm and 644 Nm of torque at 4,000 rpm, both of them best-in-class
figures, according to Ford. The power unit will be hooked up to the 10-speed
TorqShift automatic gearbox in all models except the F-650 and F-750, which
will retain the heavy-duty 6-speed.
The engine joins
the 6.2-liter V8 gasoline in the Super Duty lineup and the third-gen 6.7-liter
Power Stroke diesel V8. A lesser version of the 7.3-liter V8 will become standard
in the F-450 chassis cab, F-550, F-600, F-650, F-750, F-53 and F-59, as well as
the upgraded E-Series. It will kick out 350 hp at 3,900 rpm
and 635 Nm of torque at 3,900 rpm.
