Maybe I missed something, but, the last time I read about the internals of a 4.6L and a 5.4L (this was before the V10 even came out), the only major differences were the tall deck block (for the longer crank arm), and the wider intake (a result of a taller block). The pistons, bearings, and I THOUGHT rods were interchangeable. Appearently I over looked the part about rod length. For that, I my have stepped on my ----.
As far as the statement about 4V heads not performing as well on the 5.4L, I haven't read anything for or against that statement, but that badass 5.4L in the Ford GT speaks for itself.
But the point still stands, long stroke better torque, short stroke, higher rpm range.
