The Off-Road Truck Avenger is designed specifically for off-road applications.

The Truck Avenger features a quick change vacuum secondary for easy fine tuning, four vacuum ports for all necessary vacuum accessories, factory preset electric choke for easy start ups, and a built-in fuel filter. The 670 CFM Off-Road Truck Avenger is the perfect carburetor for small blocks or stock big block engines.

Notice - Due to the natural color variations of the dichromate plating process, the plating color may vary from casting to casting (within a carburetor) and from carburetor to carburetor. This is considered normal and is not a cosmetic defect. If you desire a carburetor with no color variation, please shop our black and shiny finish carburetors.
