340 stroker 422

At what rpm do you get full advance?? I forgot, did this engine go on a dyno??
Its all in around 3300 according to timing light. I never dynoed this one. Car will probably be on chasis dyno but I dont really know how to interpret the numbers with gear vendors on 727. What the impact of it is on the result. I go to the same place every time.

When I tried low octane fuel the advance was coming in much later and total was 30 degrees. It was all in at 4600 if I remember well. It didnt help much anyway. All it took was one hard hit.
