not a 396 just a 323:(

Well another reason for me to swap out the cam was compression, according to what I have in my set up -kb167 .040 over, zero deck height, 302's milled .025, gasket compressed thickness is .028, gasket bore diamater 4.060 stock stroke and stock rods= 10.50:1 compression but with that particular cam its more like 8.5:1. I have actually put 87 octane in it and it ran fine no spark knock or nothing! But when you take off from say a 25 or 30 roll the thing really pulls good from 2500 to about 5800-6000 rpm so I am hoping that the gear will fix the majority of the problem.
