Bryan, when I read that it sounds like he is saying it "should be connected to manifold vaccume", & that is what I did, & that is what edelbrock says in the owners manual if you can't get enough ported vacuume, as in a long duration, high lift, radical camshaft.

Everything I've heard, read, seen, experienced says the vacuum advance should be hooked up to ported vacuum not direct.
