John, the distributor is a stock Mopar replacement unit from a parts store that was bought years ago (not a Mopar Performance unit). It was recurved some time ago and has one heavy spring and one light spring. It seems to be working find. I have thought about replacing it with a known good MP unit to see if that would help.





was it recurved by just changing springs ? if so you probably have too much total timing since std mopar distributors have 30 plus degrees of mechanical advance , changing the springs does nothing to change that . But that's not your problem here .
