Update:
When I pulled and plugged the vCan that solved my popping problem. Motor runs pretty good and I got the idle down to 800 in neutral by turning the idle speed screw. I put a timing light on it and it was at 40* advanced. Wth? I'm wondering how it can idle that low and smooth with 40* initial advance? Is it possible that the dizzy pickup wires are reversed?
FYI, it has a Mopar distributor with HEI.
