How much initial, distrib ,and total advance?

I run the exact same setup, old style, and I like the linear in mine. I have done some break out curves, but mostly when its a very hot car with lots of initial and needs a very quick snap.

If I were you, break out that chart and figure out what you need to have everything in by 2500 is, basically you''ll figure it out in blocks of 1000, read it close then take a pencil and do the line chart it'll tell you which springs. I think its light green matched set? but thatsa guess, if you get stumped email me at My427stang@cox.net and I'll go look at the chart again, the chart is a little goofy until you get to know it

I'd go 14 initial, 24 in the dist all in by 2700 (2500 if you feel brave LOL)

Now, here is the kicker, when you go to smog it, recurve it again, its easy. In that case put it at 6 initial and swap the springs to come in late (>3000) it'll run crappy, but I bet it passes, then swap it back to the known good curve when you get home
