I'm trying to maximize the combination in my car. I'm running a 440 based 493 with 10.8 squeeze, MP '509 cam, Edelbrock RPM heads and intake, 2" TTI headers with 2 1/2" exhaust and a BG 850 VS carb. It is jetter 85/92 with a 3.5 PV. I set timing to 17 degrees inital, topped out at 31 plus vacuum...
