Thanks for the welcome, I feel like I know most folks from spending time reading (to much wife says). A little more info on the B7ME, heads are ECZ-G which is good and possibly original with block. The manifold is an ECZ-9425A and the carb is a manifold staining Holley 4150, 1850-9. The manifold has a spacer to carb but not sure if it is tapered or stepped. Runs good doesn't smoke, but drips all over, it was purchased in WA and driven home.
Haven't done much to it yet, the point gap narrowed on the trip home and after reset I found that there are two timing marks, I assume one at tdc and I used the other for initial distributor set, which works OK, runs and idles fine.
I started my post here because I do have questions, first is after determining tdc is there a degree calibration which can be attached to damper for a true understanding of where the timing is set and to view exactly how it responds at total advance?
