So am hoping to get some estimates on power for my streetable 572 Hemi. Its 9.5-1, .628/.648 242@.050 cam, 112 lsa, stage5 intake with a pair of quickfuel 770s and stageV heads with the attached flow numbers. I am guessing around 640-660ish. Tim

720 with a good tune and fuel.

If you even had 1.2 HP per ci thats 680 hp... 1.3 is
about 745hp.... at 1.2 which is pretty easy to make
you should be looking at 680

The only good thing about this motor having low compression is the fact that I can refill anywhere, we have 85 octane in the mountains so with that low of compression, it should run fine. Tim

680-ish with wall to wall mega-torque.

Flows through .600 are about equivalent to my Chapman Max wedges on my 517, with that little High torque broomstick cam and 572 cubes you're gonna have a hard time hooking up when you lay into it!

The thing about really good flowing heads is that even with a small cam the power/RPM doesn't fall off nearly as severely past the peak as most people might think they might

I thought about having Tim Banning CNC them but then reality check said why? I have more power than I will ever use, even for the occasional trip to the track. Tim
