No, the Q-jet that I got was not one with the power enrichment circuit. They're just plain trouble and annoying. As far as the power goes, my 350 runs well with a modified "068" cam and a set of ported cast 16 heads. I've run a 750 cfm, and it just didn't pull at the top end like this one does.
I did just like you said, matched up the gaskets, and ran into problems with the secondaries not activating. I think what the deal was, was that the 1st gasket I put on didn't have a vacuum signal port for the secondaries. So I could open them up, but the air doors didn't open, and subsequently didn't meter any fuel. I don't know what the deal was, I was hoping someone had ran into it before and had figured it out. Thanks for the input Restore60s.
