Go to budget dizzy

It really is not abour electronic, best box in the world best bang for the buck, run from points to old a system. It is all bout the curve. 90% of the ones you buy are set up for lets say the strip where they get really fast advance at say 1200-1500 crank rpm like the MP ones. Best thing you can do if it is a stock system is get one with a curve defined in section 8 of the FSM. Forget the parts strores they are set up for a 10 year spread usually and really a crap shoot if it will work PROPERLY for you.
