Review ROCHESTER Pontiac Quadrajet Carburetor Cfm Level Rebuilt And Upgraded fits 800

The Rochester RQ800P-L1 Quadrajet Carburetor is a high-performance fuel delivery system designed specifically for Pontiac engines with an 800 CFM air flow requirement. This carburetor is a part of the Quadrajet series, which is renowned for its ability to deliver precise fuel metering and excellent idle qualities.

The RQ800P-L1 Quadrajet Carburetor features an 800 CFM primary venturi, which is capable of supplying ample fuel to high-performance engines. The carburetor is equipped with a power pulse secondary system, which utilizes a set of secondary venturis that provide additional fuel during acceleration.

This feature is particularly useful for those who are looking to extract maximum power from their Pontiac engine.

The RQ800P-L1 Quadrajet Carburetor also comes with a built-in accelerator pump and a power valve. The accelerator pump provides additional fuel during heavy acceleration, while the power valve helps to maintain a consistent fuel mixture during steady-state cruising.

The carburetor housing is made of cast aluminum, which is both strong and lightweight. It also features a polished finish that not only looks great but also helps to reduce air turbulence for improved performance. The carburetor comes with all necessary mounting hardware and gaskets for a hassle-free installation.

In summary, the Rochester RQ800P-L1 Quadrajet Carburetor is a high-performance fuel delivery system that is specifically designed for Pontiac engines with an 800 CFM air flow requirement. Its adjustable secondary system, power pulse secondary system, and built-in accelerator pump and power valve make it an ideal choice for those looking to extract maximum power from their engine while maintaining smooth power delivery and excellent idle qualities.
