[QUOTE="bandit_60, post: 2470052, member: 590854"] if it has a vacuum advance then hook the hose ported ( above the throttle body ) if it,s hooked straight to the intake then it can,t advance itself for more power. if your going to throw a timing light on it you will need to know where it times at, like 6 or 8 degrees. mark the timing scale at 6 or 8 whichever it calls for and there,s a line across the damper too which has to be marked. loosen the distributor, hook up the light, start your engine and let it idle, aim the light down to the damper, turn the distributor until the line is lined up with the right degree and tighten the distributor.
