Distributor Over-Advancing

I...........do..........not........like..........."dial up".........timing............lights.

I've seen about 3 now that were off and that is enough. Recommend you scare up an old school "regular" light and check it with timing tape, or else measure around the damper calculate the advance degrees vs inches around and put a temp mark where it should be

Also you might check with TrailBeast, as I'm not "rememering" what if anything you must do with the extra pins on the HEI...........which have a timing function in the OEM installation
