Re: Holley Question
600 should be fine on that motor, i'm running a 650 double pumper on my 383 and could use more, the pinging your having could be timing too advanced, back the timing off and see if that fixes your probelm, that engine should run good on regular unlead because it's not over 10:5 to 1 compression, a carb won't cause one to ping hope this has helped
