Title: flow rating 17056263 vs 17056261
Post by: dhopkins52 on August 05, 2012, 04:02:27 PM

Is there any difference in the flow rating for a 17056263 from a 76 400 Pontiac versus a 17056261 from a 76 455 Pontiac.

All of the later front inlet Pontiac carburetors (non CCC) are the same castings.  They still may have different "flow ratings" as the 301 carburetors had a longer stop for the secondary airflaps, most of the others had the same length stop.....Cliff
