Quote: From the 4 inch throw small block posts on here over the years It seems that the smaller cid 408 to 416 with good heads 300cfm to 330cfm make peek power around 6500 to 6800 with cams in the 260 to 270 @.050 range.... There really are too many variables for a rule approach
Well my cam is 276 @ .050 and I need it to turn 7000-7200. I don't think that will be a problem.
I would think with 276 on the intake low 7s would be easy, Are you gona advance it 4*
Actually it should have been in at 108 but I had to move it to 104 to get valve to piston clearance.
.... you run that much exhaust duration & lift... Must be a nitrous engine
