.650 Super Sucker Alm. Carb Spacer - 4150

The .650 Super Sucker Alm. Carb Spacer - 4150 from HIGH VELOCITY HEADS is a precision aluminum carburetor spacer engineered for square-bore four-barrel carburetors on high-performance engine builds. Carb spacers serve as critical insulation and tuning components between the intake manifold and carburetor, reducing heat transfer to the fuel charge and enabling more precise air-fuel mixture control. This 0.65-inch thick spacer is essential for enthusiasts targeting improved throttle response, better cold-start characteristics, and optimized fuel atomization on race, street performance, and modified engines running 4150-pattern carburetors.

Machined from lightweight aluminum and polished to a refined finish, the .650 Super Sucker Alm. Carb Spacer - 4150 delivers both functional and aesthetic benefits. The 0.65-inch thickness provides optimal volumetric separation to minimize heat soak into the carburetor bowl while creating a larger plenum volume for improved fuel distribution and mixture consistency. The polished aluminum construction resists corrosion and heat degradation, ensuring durability in demanding under-hood environments. Its four-hole square-bore pattern ensures direct compatibility with standard 4150 carburetors, and the engineering allows for precise gasket sealing without compromise to flow characteristics or carburetor deck height.

This carburetor spacer is ideal for street rods, vintage muscle car restorations, bracket racers, and any builder maximizing carbureted engine performance. Installation is straightforward—sandwich the spacer between the intake manifold and carburetor with appropriate gaskets, ensuring all bolt holes align with your 4150 pattern carb and manifold. The compact 6.55 x 2.3 x 8.5-inch footprint and lightweight 1.37-pound construction minimize impact on overall engine bay geometry. HIGH VELOCITY HEADS spacers are trusted by professional engine builders and weekend warriors alike, making this component an affordable upgrade for anyone seeking measurable improvements in fuel economy, cold-start behavior, and mid-range throttle response on carbureted platforms.
