Tom Quad has some inciteful information. I have a question on the following:
Chart to shorten the slots if you have a non adjustable mopar distributor. Distributor degrees X 2 + initial= total 18 initial plus 14 32-36 total advance typically, every car is different. There should be no advance until 1200 rpm Then the advance should increase slowly until it is “all in” at 2400rpm for lighter cars - 2800 rpm - heavier cars
Should the advance be faster if the compression ratio is lower for today's gas?
