Carburetor Spacer - .5in Divided - Wood

The Carburetor Spacer - .5in Divided - Wood from Edelbrock is a precision intake manifold component designed to enhance carburetor mounting and engine breathing efficiency. This divided spacer addresses a critical gap in carbureted engine builds: controlling fuel atomization, managing intake air temperature, and fine-tuning mixture distribution across cylinder banks. Mechanics and engine builders rely on carburetor spacers to optimize performance in street engines, vintage restorations, and competition builds where every tenth of an inch impacts flow dynamics and throttle response.

The .5-inch divided design isolates the carburetor from direct heat soak off the intake manifold, reducing fuel vaporization and promoting consistent jetting across engine load ranges. The wood composite construction provides superior thermal insulation compared to aluminum spacers, maintaining cooler fuel temperatures during sustained driving and preventing lean stumbles common in carbureted engines. The divided configuration allows independent tuning of plenum chambers, enabling balanced air-fuel distribution to each cylinder bank—a feature critical for square-bore carburetors on dual-plane manifolds where isolation prevents cross-feed contamination.

This spacer is ideal for builders working with 4-barrel carburetors on small-block and big-block V8s, particularly those running Edelbrock intake manifolds or OEM equivalent platforms. Installation requires standard carburetor gasket kits and careful fastener torque sequencing to ensure a leak-free seal. The lightweight design—just 0.8 pounds—adds minimal inertial mass while delivering measurable carburetor stability and throttle control improvements in street and strip applications.
