With part number 3940930-EM and 5257 as alternate references, this carburetor is a must-have for those looking to enhance the power and torque of their Corvette engine.

A built-in oil bath air cleaner offers effective filtration for cleaner air entering the engine, which translates to better fuel economy and improved engine performance.

Holley's advanced design includes a built-in electric choke provision, allowing for easy conversion from a mechanical to an electric choke system. The carburetor also features adjustable idle mixture screws, allowable advance and retard adjustments, and optional power valve conversion for even greater tuning capabilities.

This Holley 4056-1 Corvette Automatic Power 3x2 Center Carburetor is designed to bolt on with minimal modifications and comes with a set of gaskets, fuel bowl vent tubes, and a new facing screen for easy installation. The carburetor is ideally suited for engines with up to 600 horsepower, making it an excellent choice for Corvette enthusiasts seeking improved engine performance in automatic transmission applications.
