Reply to "Need new carb"

George PAdmin.

The 4300D spread bore Autolite carb I've seen rated at 715 cfm & 750 cfm in Ford literature.

Day in and day out, from mild to wild, the 351C likes a 750 cfm Holley (equivalent to a 650 cfm BG Demon). As long as the carb is jetted properly, installing a 750 cfm Holley will not be over-carbureting the Cleveland.

Installing a 600 cfm Holley carb is definitely under-carbureting a Cleveland, it won't rev past 5000 rpm.
