Which carburetor would be best for a 1956 F100 with a 292 Y-Block, with an Isky E4 cam on 110 degree lobe centers, mated to a T98 granny gear transmission? I am looking at a Holley 2300, 500 CFM two barrel performance carb, and a Holley 4160, 600 CFM four barrel street carb, vacuum secondaries. Which would be best for the aforementioned engine, cam, and transmission set-up? Or, would a different carb altogether be better? I have the intake manifolds for both types. Any advice will be appreciated.
