Custom distributor curving.
Nice work. That's the chart from mopar enthusiast magazine. Ted Wagner wrote a couple very good articles on how to do that. Think it was in the first two issues.
The two light springs will bring total in between 1000 and 1200 rpm. My personal experience is that on the street they seen to run better with total coming in at about 2200 rpm Wich you get by using the stock light spring and one real light spring like you used. Curving your dist is one of those real easy things that for some reason people are scared to death to try. A properly curved dist makes a huge difference.
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.
