The secondary jets are manufactured from stainless steel, ensuring durability and resistance to wear and tear. The carburetor's needle and seat assembly are made from high-quality materials, such as hardened steel and bronze, to ensure optimal fuel delivery and longevity.

The Rochester Quadrajet Carburetor 7028280 is also designed with ease of installation in mind. It comes with a factory-set base circle and venturi diameter, making it a direct replacement for many GM applications. The carburetor is also compatible with various GM choke and air cleaner systems, ensuring a seamless integration into your vehicle's fuel delivery system.

In summary, the Rochester Quadrajet Carburetor 7028280 is a high-performance, reliable, and durable fuel delivery component designed to enhance the engine performance of various GM vehicles.
