I'll tell you what, I have had good luck with this method.. hold the throttle at 2000 rpm, advance the timing till the engine misses, back it off till it doesn't , go drive and listen for ping, try to start hot, retard 2 degrees at a time till any or both of those things go away. put a light on it so you know where the timing now is, drive the wheels off. for those of you running a chevy distributor, take one spring out from under the rotor and do this method, the throttle response will be heavenly.
