Ive got an edelbrock 1407 carb, just a couple quick questions. Which port does the vaccum advance line go to on the carb? Theres 3 in the front of the carb, 1 small, 1 large, 1 small. I think the first one is vaccum advance, 2nd I had blocked off on the small block, and the 3rd, is that my PCV line? graemlins/hurray.gif

The big on is for the PCV. One little one is manifold vacuum, and the other one is ported. Which one you hook your advance to, is up to you.... there's been a lot of discussion on that one. I prefer manifold vacuum.... You'll be able to tell the difference between the two ports once you start the car. The one with vacuum at idle is the manifold port. smile.gif
