Carburator Adapter w/Hold Down Bolts

The TRANS-DAPT Carburetor Adapter with Hold Down Bolts (Part Number 2062) is a precision-engineered intake manifold spacer designed to adapt Rochester 4-barrel carburetors to square-bore mounting applications. This 0.5-inch thick aluminum adapter bridges the compatibility gap between classic four-barrel carburetor configurations and modern or retrofit engine platforms that require square-bore standardization. Manufactured from natural aluminum, the adapter provides a clean, lightweight solution without sacrificing structural integrity—critical for maintaining proper fuel delivery geometry and preventing vacuum leaks that compromise engine response.

The four-hole mounting pattern ensures secure fastening and proper carburetor alignment, while the included gaskets and hold-down bolts eliminate the need to source matching hardware separately. The 0.5-inch thickness is engineered to provide adequate spacer depth while maintaining proper carburetor float bowl clearance and hood line compatibility on most applications. At 1.34 pounds, the aluminum construction minimizes intake manifold heat soak and supports carburetor stability during acceleration and deceleration cycles. The natural finish allows for straightforward identification of the adapter's condition and simplifies future inspection or maintenance access.

This adapter is essential for engine builders, classic car restorers, and performance enthusiasts performing carburetor swaps or manifold conversions. Whether upgrading an older engine platform with modern square-bore fuel delivery or retrofitting a Rochester 4-barrel onto a non-original intake, this adapter ensures proper sealing and secure mechanical attachment. The complete hardware package—gaskets, bolts, and spacer included—reduces installation time and ensures all components meet original equipment specifications for long-term reliability.
