It looks like Rochester automatic choke carburetors were made for 216/235 engines back to 1932?

They were called BC carburetors (C = Choke)

I have the standard Rochester BC carburetor on a 235 Hydra-Matic transmission on a 1954 235 truck engine. Up until that year, the BC carburetors were used only on car engines.

One thing to consider is the base mounting-hole-to-hole distance, 2 5/16" vs 2 9/16".

The 216 and early 235 engines are not "splash oilers" -- this is a splash oiler.
