On the basic laymen’s terms of cfm X 2 = a good street strip power effort that can be obtained. It is a good mathematical equation IMO while not going full tilt on the build and it certainly not the ceiling.

-TF - 301 @ .700 = 602hp
-TF - 293 @ .600 = 586hp
PM - 284 @ .600 = 568hp
PM - 286 @ .700 = 572hp

Of course, only if your lifting the valve that high and building the rest of the engine to suite and chase the above goals.

If your not......
