Dave, I know it's semantics, but the 2-valve V10 came before the 3-valve, so the F53's is an upgraded version of the one found in Axis/Vegas. In fact, my first V10 was rated at 275 HP (also 2-valve), with others rated at 305 HP.
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.
