so some follow up.
Car is still running like crap but I am closing in on it. So with some research I've learned that my HEI between vacuum and mechanical is accounting for a total of about 35 degrees advance. With an initial timing of now 12 degrees a total of 50+ degrees of timing. Way too much. So I have capped off the vacuum advance and the car is running much stronger and I heard no pinging. I still don't know total timing as the timing tape I applied the other day fell off somehow on my way to work today. I need to get a new tape to confirm total timing and then the idle mixture screws and idle itself is kicking my ass. I'm trying to set those using a vacuum gauge with no luck so far.
