Thanks for all the input guys. The engine I'm running is a 1972 402 with truck heads. I have my born with motor stored for now. From what the guy I bought the motor from told me, it has a mild cam and no head work. It's been rebuilt with a/m pistons which I confirmed when I pulled the pan, but I think they're just stock compression replacements. It's real clean and looks good inside, but I'm not expecting that much performance out of it.
I'm running a Holley 3310-3 that I just rebuilt. I was planning on hooking the vacuum advance to a small port on the base plate of the Holley. I'm not quite up on the full ported vacuum vs. manifold vacuum etc. I know enough about advance to be dangerous, but that's about it. I'm planning on making an advance limit block for it though.
Here she is:
