What is your interpretation of these advance springs?
I'm going to post a picture showing the differences in the springs. The rusty stuff on the left is original 1963 225 Slant stuff with an 11.5 mechanical advance, and the clean stuff on the right is the newer reman '70's distributor with a 13 mechanical advance. Notice that the older distributor has a heavier primary spring and a shorter loop on the secondary spring.
How is this going to affect the advance curve?
