I liked the Carter AFB carburetors but getting jets and metering rods was not easy for an 18 year old back in the 60s. Metering rods and springs could be easily changed externally, and the spring compensated secondary air valve was also easily adjusted externally.
I had a pair of AFBs on an Edelbrock C36 (IIRC) 2X4 intake on my 64 Impala SS with very highly modified 327. Progressive linkage. Could drive around all day on the front two venturis of the rear carb. Front carb was the front carburetor from a 2X4 409. It has no choke mechanism, idle circuits or secondary lock outs. 2X4 409 air cleaner bolted right on, and I fabricated an Oldsmobile W30 style ram air system with 6" air inlets made from furnace ducts mounted below the front bumper. They were big and caught lots of air at speed.
Quadrajet carburetors were wonderful performance carburetors for OEM applications. Economical small front venturis and very large secondaries. Kind of like having one's cake and also eating it.
Holleys were suitable only for high performance applications where economy didn't matter. Very uneconomical and would leak after a short while.
