My YF 966S spec sheet says:
Chevrolet Power Glide and Truck 1950-52 for 3-9/16 bore, 3-15/16 stroke.

Chevrolet lost sanity in 1950 and switched from Carter to Rochester.
The YF-966S is a replacement carburetor for the 235.

My YF 2100S spec sheet says:
Chevrolet Truck 1953-56 for 3-9/16 bore, 3-15/16 stroke.

The YF-2100S is a replacement carburetor for the 235.

The question I would like to have answered is, if I had a choice of either, which one would work better on my 261?

"Adding CFM to a truck will only help at engine speeds you don't want to use."
