Thanks Guys!

Superbeedave, sounds good I will give it a try. Currently I am running a MP distributor with the springs that came in the distributor and it is running all in by 2700 rpm. Timing is set to 17 base and 33 total. Running a 500 cube 11:1 all street motor.

At what rpm should the mechanical advance start and be all in at what rpm?

What do you guys recommend?

Rick thanks for the instructions.
