Just to set the record straight, we manufacture kits for EVERY Rochester produced from 1949 Olds (ugh) to and including 1974 including the (pass the Advil) Olds Jetfire sidedraft type R and RC models. All single barrel, 2 barrel, and 4 barrel Rochesters in this era.

Just require identification of the carb.

The most expensive carburetor is the wrong one you attempt to modify.
