That's correct

The OHC motors just aren't good truck motors. That V10 is gutless compared to a 460 and doesn't get much better gas mileage while being bigger and far more complex.

I'm sure most people know the story, but Ford's mod motors were designed for FWD applications. That's why they are short but wide. When the FWD didn't pan out, they had no choice but to put them in other vehicles. It may be a quieter, smoother motor, but quiet and smooth doesn't get you out of the mud or get your boat up the ramp.
