Warren,something is way off the mark here. You are basically running no timing, with race gas, and you have detonation. What have you got for pistons in that thing,and what head casting number do you have? Do you know what the ignition curve is? Have you checked your balancer against TDC to see if it's slipped?

Warren,what was being suggested to you,was a check of the balancers TDC mark against the actual TDC position of the #1 piston.
