okay, thank you very much for the info.
I am just trying not to buy 2 distributors. The one i have now either starts the car great but has no top end, or has great top but won't start for sh!t. also it seems to run the exhaust very hot, im thinking this is too late of timing causing more to burn in the exhaust than it should.
anybody have a good timing recommendation for a mild 383?
You need to get the distributor AND the box on a distributor machine and set the curve and account for the retard in the box. Once you fix the curve, what you have will work.
You nee to check the timing at idle RPM and then check it again at or above 5000 RPM to see what it has at idle and rev up
It sounds like your current distributor may have one weight stuck and that is not letting the mechanical advance work properly
I like to see from 12 to 16 degrees advance before top dead center at idle and right at 34 to no more than 36 degrees advance before top dead center revved up

Stock Mopar distributor are not hard to fix or modify to make them better for performance use, I do my own and have had really good luck with them, my current S/P car runs n the high 8s at 150+ MPH with one I modified
