Associated Comments:


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 inch x 5 5/8 inch 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.
