The comp you have is fine with that motor its actually pretty good. The problem is not initial its total get tha low comp up timing wise and and forget the 36 total crap Mopar preaches,The 36 toatl is for 9-10-11 one comp not some lean burn cast off 360. Try to find a Accell dual point dist put it in stock and set the total starting at 44 degree's, and try it you will love the way it performs provided everything else is up to snuff/ put a 650 dbl pumper on it and go have fun. Insist on TQ then tighten up the air valve so that it will not just flop open like the factory settings with the old weak sec springs that it probably has in it. By the way oif this combo is wrong then guess what I'd rather be wrong and fast then right and slow
