An acquaintance provided me with a 1955 235 engine. It came with a Rochester series B carb, automatic choke. I would much rather have the manual choke. Is it possible to use the Carter YF on my '55 235? The hole spacing on the bottom section (carb to manifold mount) doesn't quite match, so I would presumably need some sort of adapter.

It would be simpler to run the 216 intake manifold on the 235 with a set of stepped-up alignment rings than try to adapt the Carter to the wide-spaced 235 mounting flange.

I believe model 2100s would fit your engine.

They are nice to have when you want to install an intake that was made for a 216 on a 235 or in this case. That being said, I am pretty sure there are later YF's or YFA's with the larger bolt pattern although I don't know whether the larger YFs came with manual choke.
