This model of carburetor has the square bore flange bolt pattern. It can replace Holley, Edelbrock, Carter AFB, and Autolite style carburetors with 5-3/16" x 5-5/8" bolt pattern. If you have a spreadbore style intake manifold, you will need an adapter to install this carburetor. Similar to the Mr. Gasket #1932.

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.
