Yes that is the chart from Mopar Enthusiast. I did find that a slot length
of .375 gave me one degree less than posted though or two on the crank.
I had the one light spring and one from a Mr. Gasket spring kit and all
my advance was in at 1500 rpm. Tonight I will try it with the two
stock light springs and hopefully that will put me about 2200-2500. If
not I will have to play with the heavier spring. It's important to keep in
mind that shortening the slots also changes the spring rates too so that
the .100" I shortened the slots might put the stock spring rate about right
on for me. I'll keep you posted.
I hope all this info saves others time, and don't be afraid to dig into it.
It's probably the cheapest performance booster you can do!
I am far from an expert so if anyone sees error with my posting please let me know.
