In the hands of the right tuner, the pre-electronic QuadraJet carburetor is one of the best street carburetors extant!! It isn't simple, but it is so tunable that GM made it work for engines from 230 cubic inches to 455 cubic inches with the same basic configuration. This isn't including the larger unit made for the 500 cubic inch Cadillac, (which,by the way, can be made to work on even larger displacement engines)!!
Tuned properly, it works better, (all around) than any other non-electronic carburetor ever made for the street. Once you get it sorted out, you close the hood and forget about it!!
Granted! Tuning isn't "so simple a caveman can do it", but it ain't "rocket surgery" either!! John Lingenfelter wrote SVERAL articles on it and explained it step by step in vivid detail!!
For smooth, everyday use and performance, I STILL like a Qjet for non fuel injected projects.
