Topic: autolite 4100 big block vs. small block

[socalgt]

Is there any difference between the 4100 carb(C6AF-F 1.08 venture 480 CFM) for a big block vs. small block C6ZF-B 1.08 venture 480 CFM).  Both are for automatics and appear to have the same specs.  Are there internal differences that would make them not interchangeable?

The carburetor bodies are likely the same. I would imagine that the linkage is different.

I thought the BB used the 112 venture?

cfm's might be different and surely jetting or metering is
