Brand New Holley Street Avenger Aluminum Carburetor, 670 CFM, 4150 Vacuum Secondaries, Shiny (Part #0-81670).

Street Avenger carburetors are known to bolt on right out of the box and have great features such as a quick change vacuum secondary for easy fine tuning; optimized street calibrations;  four vacuum ports for all necessary vacuum accessories; factory preset electric choke for easy start ups; built-in fuel filters; and an included fuel line kit so there are no unnecessary trips back to the parts store.

The Avenger series are the first carburetors to have a limited lifetime warranty. With a great warranty like that and the included comprehensive instruction manual, you can count on years of worry free service.
