Carb Selection

Thats a pretty small cam for that motor. I have a bigger solid lifter flat tappet cam in my 426 low deck, 383 with 440 crank. The 850 will be more than enough for whats there. Get a carb with 4 corner idle, and make sure you run a power valve on the primary side. Your deal at 6000 rpm works out to 763 cfm. My motor used 638 cfm on the dyno, i have an AED 750 HOM dbl pumper. flows 830 cfm. motor runs great in the car and the throttle response is very crisp.
