650 CFM - Mechanical Secondaries - Shiny - Gasoline - Manual Choke. Same hardware and benefits as the model above: side-hung bowl simplicity, universal throttle lever compatibility, mechanical-secondary immediacy, and modern calibrations—ready for quick installation and easy tuning on street-driven builds.. 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.
