I have a stock smogger 440 that runs well and has good even compression numbers.I may play with it a little and swap some closed chamber 915 heads I have on it and of course a cam as well.
What would make a better running motor in a heavy c body with 3.21 gears and an 11" converter?

A comp 260 High Energy ground on a 113 lobe separation(have one here already) or some thing like a Hughes Whiplash design?

Which would you use and why?
