I am looking for a carb for a buick 350. Went to the storage building to get one and they have been moved on me . All are in one pile 350 and 455. Is there an easy way to tell them appart or do I have to look them up somewhere?

The 455 carb will have the larger primary venturis. Look approx 1/3 of the way into the primary on both carbs. The larger carb will be missing the "ring" containing the metering components. It will have only a "bump". This may require a critical eye and plenty of light... it will not require disassembly, just a hairy eyeball. Ray
