So if they are flowing within 10%, they could be flowing 284cfm @ .650"? Or is it 274cfm @ .650"? Which heads really? The big mouth heads are listed at 316cfm @ .650 and the fully cnc'd heads are 304cfm @ .650". 90% of those flows is......well......284 or 274.

Not that is isn't the cam, just wondering.

It's not the goddamn cam on its own. I'm just gonna say it--The heads ain't the power producing beasts you think they are. I have the BIG csa heads and they still don't move air the way they should. It's not just the numbers, its the way they sound and the shape of the curve.

I built a 417--with Max ported EQ's and custom roller cam--made 581 hp / 563 tq. Wasn't happy with the power down low, (IT WAS JUST LIKE YOURS IT MADE 400-440 TQ FOREVER AND COULDN'T GET OUT OF ITS OWN WAY UNTIL ABOUT 4800 RPM)put a smaller Lunati Voodoo roller and W2 heads that flowed LESS and made an easy breezy 590 HP / 574 tq! Still didn't crack 600HP and I really wanted to. It's time somebody said it. 600 HP small block on pumpgas ain't happening with a standard port head no way -no how for the average man and budget. And I'm average. J.Rob
