    Hello everyone I am rebuilding my 1972 Ford Maverick Grabber and am looking for a compatible 4 barrel carb. Anyone have suggestions?

    If it is mainly stock or slightly modified, the Summit branded 600 vacuum secondary sum-m08600vs or a plain Holley 600 vacuum secondary will do the trick. I have had both, but I prefer the Summit.

    Welcome to the site from northeast Ohio!!!

    As jasonwthompson states, the Summit Racing 600 cfm vacuum secondary carburetor is a great unit even with a modified 302 engine.

    A 600 CFM is what everyone buys and generally work very well.

    Truth be it known, a 600 is overkill for any 302 with stock heads. Calculating volumetric efficiency of 80%(generous) spinning to 6000 RPM only requires 472 CFM. Maybe Ford knew what they were doing when they specked the factory 289/302 4bbl at 470 cfm.
