cfm to horsepower

Auto math question.I found a flow converter that says at 28"wc .256 X CFM X number of cylinders will give you potential horspower.But at what valve lift.I want to know how much CFM I would need to flow to potentially produce 500HP at .600 valve lift.Can anyone help with this quetion?

Isnt this an easy one: 250 cfm?
I have used this rule of a thumb : intake runner flow x 2 = horsepower potential.
Compare these figures to each other and you´ll notice that this simple rule works.. well enough for us average hot rodders [img]/phpBB/images/smiles/icon_rolleyes.gif[/img]
