Engine Math
I have a formula where you can get estimated HP based on CFM of headflow.
HP=.2575 x CFM(@ 28" of H2O) x number of cylinders
Does anyone know if this is an accurate way to calculate HP?
Also this is for a 350, does anyone know how you could calculate for a 383, 396, 409?
(I got the formula off the back of the AFR catalog.)

Re: Engine Math (Epyon127)
If that was true, all you wouild have to do to get bunches more power would be swap to heads with bunches more flow.
If only it were that simple.
If you change everything else in the engine to where it will support the head flow, then there might be some truth in the formula...up to a point.
