I'm unsure how such a calculator as this would take into account unknown engine variables, but such as it is.... here it is. Any constructive feedback would be appreciated. My engine is a BB 533 with 650FWHP, 2" headers, Trickflow heads, ported, Vic Jr. Intake, Demon 850 annular carb. I don't have the cam specs at hand.
