Does anyone know why the new Ford "Godzilla" V8 7.3 liter is rated at 350 HP in a Class C motorhome but 430 HP in a Ford F250 superduty truck? The torque ratings are similar though,
I would guess it's de-rated because of the heavier duty application. Also, cooling may be an issue with the tighter confines of a van engine compartment versus a truck engine compartment.
