Sometimes you over look some of the dumbest things and kick yourself after. LOL
Yea, been all around this problem for a while. Good SFI balancer, tried 30 to 40 deg total advance,(not any power above 34 deg.) all in by 2300. O2 sensor on dyno shows 12.5 a/f ratio, tried BG850 Mighty Demon as well as the Holley 750 dp. I'm gonna degree the cam this weekend just to see how it was installed, then pull it to check the part no. and lobes. BTW, it runs 12.40's, but I know I'm down a bunch...
