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.
Holley's Street Avenger line of carburetors has a reputation for bolt-on-and-go performance. They have great features including a quick change vacuum secondary for easy fine tuning, optimized street calibrations, four vacuum ports for all vacuum accessories, a factory preset electric choke for easy startups, built in fuel filter, and an included fuel line kit so you don't have to make multiple trips back to the parts store to get your hot rod back on the road. These carbs share all of the same features that the Street Avenger series is known for, but now with a 36% savings in weight. Being aluminum also means they will hold their shine longer! Street Avengers are ready to run right out of the box, and now they are better than ever! Saving weight optimizes every aspect of performance of your car, whether it is acceleration, braking, or handling. What better place to start than the top of your engine?
