The Rochester Quadrajet 4-barrel carburetor, model number 17058477, is a legendary piece of automotive history that continues to be sought after by enthusiasts and classic car owners. This particular carburetor is designed for use with 1978 Chevrolet 350 engines, offering an impressive airflow capacity of 800 CFM.

The Quadrajet 4-barrel carburetor is renowned for its ability to deliver a smooth and consistent fuel flow, ensuring optimal engine performance.

The housing is finished with a smooth, polished surface, which not only looks great but also aids in the smooth flow of air and fuel.

The Quadrajet 4-barrel carburetor comes with a set of four 1.5-inch primary throttle bodies and one 1.75-inch secondary throttle body. Each throttle body is equipped with a high-performance accelerator pump, which ensures a consistent fuel supply during acceleration. The carburetor also features a built-in choke system, which helps to improve cold engine starting and warm-up.

In conclusion, the Rochester Quadrajet 4-barrel carburetor, model number 17058477, is an excellent choice for classic 1978 Chevrolet 350 engine owners looking to improve their engine performance.
