Given all the info in this thread, here is my plan of action:
I'll start by setting my baseline timing to somewhere around 12 degrees. I'll then get the dist. curve set to provide about 30-some degrees of timing in before 3,000 rpms. I won't worry about vacuum advance for now...just leave my adjustable unit alone.
Once the timing is squared away, I'll play with the carb. I'm thinking of dropping my idle to about 600-650 in gear (depending on if it is smooth enough for my liking) and trying the cams in position 1. Just for fun. If i get it close and can live with the lower idle, I'll use that.
Sound reasonable? Any initial starting points, such as which pump cam, which distributor springs, etc that can be suggested (rather than trial and error)?
