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 new all aluminum 0-80459SA carburetor is designed for the rodder who needs 750 CFM of airflow, but only wants a single fuel inlet or is building a 2 x 4 setup. Its single feed fuel inlet, vacuum secondaries and electric choke make it amazingly universal. Don't trust your performance to just anyone, Holley is the only modular carburetor company that has been in business for over 100 years and has powered every NASCAR champion since the 60's.
