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 all-aluminum 0-80458SA carburetor was designed for the rodder with a mildly built engine and a desire for a racy dual inlet look, but who only needs a 600 CFM carburetor. Dual feed fuel inlets assure you get all the fuel you need while its 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 '60s.
