Carb Adapter 2bbl-4bbl

The MR. Gasket Carburetor Adapter 2bbl-4bbl (Model 1933) is a precision aluminum spacer engineered to bridge the gap between 2-barrel Holley carburetors and square-bore 4-barrel intake manifolds. This 1-inch thick adapter delivers a clean, direct connection without requiring manifold modification, making it an essential component for engine builders performing carburetor conversions or modernizing older carbureted platforms. The gasket and hardware are included, eliminating the need for sourcing additional sealing materials.

Manufactured in aluminum with a natural finish, the adapter weighs 1.55 lbs and maintains strict dimensional tolerances to ensure proper seating and seal integrity. The 1-inch thickness provides adequate spacer volume while preserving proper carburetor-to-intake geometry and fuel delivery angle. The open design allows full airflow characteristics of the carburetor to remain uncompromised. All fastening hardware is included for immediate installation, and the adapter accepts standard gasket materials for reliable sealing across ambient temperature ranges typical in street and race engine applications.

This adapter serves engine builders, restorers, and performance technicians converting 2-barrel carburetors to 4-barrel manifold platforms—common in fuel-injected-to-carbureted conversions, vintage hot rod builds, and carburetor swaps where intake manifold compatibility requires an intermediate spacer. The MR. Gasket brand is recognized in the automotive performance sector for precision carburetor components and gasket solutions.
