I talked to Kenny at Indy about this, and he said to get them over 400 CFM you had to do blending of the seats and bowls and you had to thin the margin on the valves. He also said he doesn't recommend thinning the margins on street motors because it hurts the reliability. I use mine on the street so I left the valves alone to keep the reliability. 68 cuda formula S 588" bb 5sp 70 CUDA CONVERT 500" 5SP (SUBLIME) 70 CUDA CONVERT 500" 5SP (PLUMCRAZY):TOO MUCH HORSEPOWER, IS ALMOST ENOUGH!

Jeff's the exhaust is with an extension, Dwayne's are not. The motor made around 850 HP. BTW, they were hand ported by Barton, All Jeff and Dwayne did was flow them and freshen them Jim

I don't run a .800 lift cam, more like .730"ish with lash. Mine @ 342 CC seem to hang with the best of them up to around .500 lift. There is a a lot to be said for a low maintenance combo with springs that will live all season.

Indy CNC 440-1's in a tube chassis car, and the switch to Indy's 572's were worth less than a tenth NO OTHER CHANGES. Engine was a 572 inch Indy maxx block motor with 14:1 compression running a 4" toilet alky injected...
