"Godzilla" Ford V 8
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,

Engines are normally de-rated for ‘severe service’ applications like an RV where there is no such thing as “empty miles” like the majority of driving is with a pickup truck or even a cube van. It makes a big difference in durability and longevity.
In Ford’s case, it was something they’ve been doing from their earliest days with their farm tractors.
As an example, a ‘typical’ Ford tractor, a 3000 utility tractor has a 2.6 liter (158 cu. in.) gas engine, de rated to 46.7 hp. By comparison, a pretty well-reputed typical automotive engine, the Mitsubishi 2.6, is rated at 135 hp.
We have a Ford 3000 gas tractor, the engine has had (or needed) anything but maintenance since it was produced in 1965, it currently has a little over 10,000 hours on it. If you use the conversion speed of an average of 45 mph, that would suggest it has the equivalent of 450,000 miles on it. It still has no real wear evident, no oil consumption or blow by, etc.
