This carburetor features a classic design that will complement the look of many street rods. The polished aluminum finish adds a touch of elegance to the engine bay, while the black base provides a contrast that makes the carburetor stand out. The carburetor also includes Holley's classic bowl-mounted floats, which provide accurate fuel level sensing and help maintain a consistent fuel mixture.
