The Rochester 4GC Carburetor is constructed from high-quality materials, including brass and stainless steel, to ensure durability and longevity. The carburetor body is finished in a satin chrome plating, which not only looks great but also provides a protective layer against corrosion. The carburetor base gasket is made from a high-temperature, pressure-sensitive material to ensure a secure seal between the carburetor and the intake manifold.

This carburetor is a direct replacement for the original equipment on 1956 and 1957 Oldsmobile models. It is important to note that some modifications may be required to adapt it to modern fuel systems, including the installation of a fuel pressure regulator and an electric choke. It is also recommended that the carburetor be properly synchronized with the intake manifold and the distributor to ensure optimal engine performance.
