Is there anybody who knows what kind of carburator I need for Buick Iran. It has a 350 v8 engine. I also have a blazer 1977 which has a 400 v8 engine. I do not know what kind of carburator I should buy. I have checked partsamerica.com but there are so many choices. Does anybody know what I should buy for my blazer or buick?
If it has a 4 barrel manifold, and is street driven, the best carburetor would be the stock Rochester Quadrajet. It offers the best balance of power, economy, and driveability. You can get a rebuilt unit at your favorite auto parts store(you'll have to pay the core charge if you don't have an exchange), or you can get them at swap meets, and have it rebuilt, and or jetted.
