Here's the question.:
The build includes - Cam .540 lift, M1 intake, 392 cui stroker, 800cfm carb
With ported 589s (2.02 valve) that flow [email protected] the engine makes 420 HP
With OOTB RHS heads that flow 255 @ .550 it might make around 435 HP?
With "hyperported" Eddies that flow 300 @ .600.............would it make any more HP ?
............or is there a point that the heads won't show any improvement?
In other words...is there an "ideal" port peak flow # and how is this calculated?
(Assume the intake is gasket matched etc and best valves etc.)
