Well, this may sound stupid, or it may actually have been done before, but since I'm curious, here goes: I found a 4 bbl carburetor in my locker in the garage that went on a 1982 Dodge Travco Motorhome we used to have. (A 440 powered that thing.) Anyway, I was flirting with the idea of seeing if it was possible to get that onto my 318 in the Fifth Avenue I have. It would definitely need a new intake manifold, but other than that, I don't know if this is feasible. (I would also have to remove the lean burn, inherently, because this carburetor does not support that.) I think the carburetor is a Thermoquad, because if I remember right, it's got that black piece of plastic that is known on the bottom. Any thoughts?
