Carburetor Adapter w/ Hold Down Bolts

The Carburetor Adapter w/ Hold Down Bolts (Part Number 2064) is a precision aluminum adapter designed to facilitate carburetor mounting transitions. This 0.5-inch thick unit converts from square bore to small square bore configurations, making it essential for engine builders and performance technicians managing carburetor compatibility across different manifold platforms. The adapter ships complete with gaskets and hardware, eliminating the need for sourcing additional sealing components or fasteners.

The four-hole mounting pattern provides a secure interface while the aluminum construction balances weight and durability. Natural finish allows for custom finishing to match existing engine bay aesthetics or protective coating application. At 1.33 pounds and compact dimensions (7.2 x 1.4 x 8.6 inches), this adapter integrates cleanly into tight engine compartments without adding unnecessary bulk. The inclusion of hold-down bolts ensures proper fastening security during operation, critical for maintaining carburetor alignment and preventing fuel system leaks or vacuum line disconnects.

Engine rebuild projects, vintage vehicle restorations, and performance swaps frequently encounter carburetor mounting mismatches where original manifolds lack compatible bore configurations. This adapter solves that integration challenge for hot rod builders, restoration shops, and weekend mechanics working with mixed-generation engine components. Whether upgrading a classic platform with modern fuel delivery or consolidating manifold inventory across multiple build projects, the adapter's included gasket set and fasteners eliminate ancillary sourcing delays.

Square bore carburetors remain standard across Holley, Edelbrock, and Performer-series manifolds. This adapter's standardized bore-to-bore transition makes it a practical inventory item for shops managing legacy engine platforms alongside modern builds, reducing lead times on compatibility solutions.
