Moroso 64952 Phenolic Carburetor Adapter 2-Barrel to 4-Barrel 1 Inch

The Moroso 64952 is a phenolic carburetor adapter designed to mount a Holley 4412 500 CFM 2-barrel carburetor onto a standard 4-barrel intake manifold with a square bore Holley 4150/4160 bolt pattern. This 1-inch thick adapter provides a reliable solution for engine builders looking to adapt a 2-barrel carburetor configuration to a 4-barrel manifold setup.

Key Features:

• Constructed from phenolic resin for superior heat insulation properties
• 1-inch adapter height for proper carburetor positioning
• Individual venturi port design for optimized airflow
• Heli-coiled threaded inserts for increased durability and strength
• Adapts Holley 4412 2-barrel carburetors to standard Holley 4661 bolt pattern manifolds

This adapter is sold as a complete kit with all necessary mounting hardware included. The phenolic construction helps prevent heat transfer from the manifold to the carburetor, reducing the risk of fuel percolation and vapor lock. Gaskets are not included and must be purchased separately.
