The Quadrajet carburetor's housing is made of a durable cast aluminum material, which is not only lightweight but also resilient against engine heat and corrosion. The carburetor's exterior is adorned with a chrome finish that adds to its aesthetic appeal, making it a desirable addition for any classic car restoration project.

This particular Rochester 7041257 Quadrajet Barrel Carburetor is compatible with various GM applications, including Chevrolet, Oldsmobile, and Pontiac vehicles from the late 1960s and throughout the 1970s.
