• This carburetor features a square bore flange bolt pattern, allowing it to replace Holley, Edelbrock, Carter AFB, and Autolite style carburetors with a 5 3/16" x 5 5/8" bolt pattern. If you’re working with a spreadbore style intake manifold, don’t worry—you’ll just need an adapter for installation, like the Mr. Gasket #1932.
