I'm making this distinction to highlight that Ford didn't detune the V10 for the E-Series -- because the connotation suggests making of a cheaper product. I think the reason they didn't upgrade the E-Series to 3-valve heads may have included other limitations.
At the lower RPMs these V10 engines operate most of the time, I'm not sure it makes all that much difference to drivers anyway. I certainly don't go near 300 HP on my present one. At cruise I'm only using around 50 HP on average. My best guess is that Axis/Vegas at level cruise run around 75 to 100 HP, depending on speed.

Actually when I bought my Class C a few years ago Ford themselves classified the V2 V10 as being a "detuned" version of the V3 V10. The reason they gave is excessive heat build up in the engine compartments of the E series chassis with the V3 362 HP engine. Not my words but Ford Technical Support's. If I have the time I will go back to my email archives and find the message from their TS folks after I submitted the inquiry. At the time I was wondering why the E450 cutaway was 305 and the F53 was 362 so I asked.
As to HP, a 57 HP difference is quite significant when you are climbing through the mountains of western Virginia or NC. Not sure about others but my camping the past few years has been about 65/35 mountains to flatland. I can tell the difference in power even with the increased weight of the Class A over the C.
I do not believe, or would suggest Ford does something inferior. In fact I was ready this weekend where they have surpassed Toyota in reliability ratings. When they get to be inferior is when I'll sell my stock.
