big block chevy 496 vs 466
4.31 bore 13-1 compression
stroke off 4.00 6.385 rod r/s of 1.596 vs. stroke of 4.25 6.385 rod 1.502 r/s

any thoughts on rod stroke ratio. i have seen reviews on this subject from it means nothing to it is one of the most critical things in a rotating assembly beside rod and crank quality steel and machining.

i would go with the better r/s ratio but it means 30 cubes and possibly 45+ horsies lost or the lesser r/s ratio and possibly have longevity issues? Will be looking for around 700 hp so what does anyone out there think of this subject.
