Ok. Honesty is good. lol Well, sans ripping into the timing cover, lets get you a better ignition curve. I can see right now the two medium springs are having some effect. What "I" do is put one medium and one light spring in. Almost always, this gets the "all in" rpm just right. Normally it's all in by 2500-2800 using that method. What you have now is probably all in by 3200-3500. Also, you need to find some way to limit the total mechanical advance. I like the timing limiter plate by FBO. You can get one here: How to limit mechanical advance in a mopar distributor, tuning for street, strip or all out racing, cure that rich stinky idle, win races
