We've already been there some pages back (not expecting everyone to read every post in this massive thread.) Offline to this thread I have worked on timing and mixture with CC member "Patrick." We started out at the dyno settings of 20* base + 18* advance (which is where it was before mounting the body.) We then went to 18+18 and we are presently at 16* initial + 21* advance for a total of 37*, all in my 3200 rpm. It does seem to idle bit cooler now than it did at 20+18. Certainly idling cleaner and not so gassy.
I also have Don Gould's Word doc entitled "4 Seconds Flat" and he advises 24* initial + 10* advance via his 10* MSD bushing, which I have lying here on my desk but haven't tried. His whole argument around FE timing is not in line with what is recommended by people on this forum, but I am trying to approach this one step at a time.
After lots of road testing and using a vacuum gauge I am 1.75 turns out on the primary and 2 turns out on the secondary, Mighty Demon 750 Annular. Plugs look great and it runs and transitions great. Car starts time after time, no strain/knocking/pinging or backfires.
