Boost is just a measure of restriction in the system. I ran 452 heads on a 383 with a 224* flat tappet cam and 7.5:1 comp. It ran 12.64 at about 13 psi. Built a new much more free flowing combo same degree duration cam better heads and little higher compression. 9:1 and ran 12.36 at 4 psi. My point is who cares what boost is as it is a measure of restriction. What did the car dyno or run on the quarter with the same pullies and the different cams?

11.67@118 1.88 60' with only 7-8 lbs of boost. Turbocharged, megasquirted, 407 BB, 440 source heads, roller cam, 9:1 comp. http://s292.photobucket.com/albums/mm14/beansgracie
