There's a mathematical solution for this, I believe you take the cubic inches of your engine, and divide that by the maximum RPM that you plan on runnin' at.This should give you a good starting point, then you need to adjust your high speed air bleeds, and jets to provide maximum performance- a dynomometer would help a lot in that situation.Good luck
