I've got mine hooked to the big port on the back of the carb, you can also use a vacume tree and put a T in your existing line. Should work like a champ

Any vacuum source that comes from below the butterflies will work, the big one on the base of the carb will do, but it is usually for the PVC, factory cars used a brass distribution block off the back of the intake for the supply.

I hooked mine into the PCV port at the back of the carb with a brass T. I'm considering drilling and tapping a new port on the back of the intake manifold like my Air Gap manifold had.
