Unless one is "building" a full race (Serious racing) engine, the only difference is the strokes. If one is "building" a full race engine, an aftermarket crankshaft would be a better choice.

Yes. They are not much different than the A or B heads that came on the the earlier 425. If the block is machined for 45° lifters, the pushrod holes must be enlarged for clearance.

Since I have been on the internet, I have seen that posted. Possibly accurate, as long as it is in neutral or park. But if, with all other factors being the same, both were accelerating, how could a 425 "rev faster" than a 455?
