GM carb on my 400

The 318 4bbl cop cars I've searched from the mid 80s all had Quadrajets on them. I don't recall seeing any with Carter cast into it, all were Rochesters. GM & Ford had the engineering $s in those days to keep up with the smog requirements. TBI and later MPI gave better fuel control than the carburetor, which I think killed off a number of carburetor companies on both sides of the pond.
