Quadrajet

The Quadrajet is a 4 barrel carburetor made by the Rochester Products Division of GM that was widely used in General Motors motor vehicles until 1990, in which its last application was on the Oldsmobile 307 V8 engine, which was last used in in the Cadillac Brougham and full size station wagons made by Chevrolet, Pontiac, Oldsmobile, and Buick.

The Quadrajet is arguably one of the best carburetors made for passenger vehicles, offering the best compromise of fuel economy, performance, driveability, and emissions control.
