Edelbrock Carburetor Adapter 2732 — Steel open-center adapter for square-bore to spread-bore, includes gaskets and monotube design

The Edelbrock 2732 Carburetor Adapter is a steel open-center adapter that lets you mount square-bore carburetors to spread-bore intake pads with reliable, leak-free construction and included gaskets.

Designed to bridge carburetor and intake combinations that weren't originally matched, the Edelbrock 2732 adapts nearly any carburetor to most intakes. Its monotube internal design, robotic projection welds and rolled-closed tube ends prioritize consistent fit and long-term durability. The adapter ships with installation gaskets and a natural steel finish, making it a straightforward upgrade or replacement part for engine builders and hobbyists.

How does the adapter ensure leak-free performance?

The 2732 uses rolled-closed tube ends and precise robotic projection welds to eliminate gaps and weak spots where leaks commonly start. These manufacturing choices reduce the risk of air or vacuum leaks at the tube seams, keeping the intake tract consistent under varying engine conditions.

• Rolled-closed tube ends prevent open seams and minimize leak paths
• Robotic projection welding delivers uniform, repeatable welds
• Monotube internal design reduces internal seams and flow disturbances
• Includes gaskets sized to the adapter for proper sealing at installation

Which carburetors and intakes will the Edelbrock 2732 work with?

This adapter is intended to mount square-bore carburetors to the spread-bore carb pad found on many Edelbrock intakes. It provides a flexible solution when swapping carburetor styles or fitting a non-original carb to an Edelbrock intake manifold.

• Square-bore carbs to spread-bore Edelbrock intake pads
• Common aftermarket square-bore carburetors used in performance builds
• Works as a universal bridging piece when bolt patterns align
• Includes gaskets to match the adapter-to-intake and adapter-to-carburetor mating surfaces

What construction features improve durability and damping?

The 2732 is built from steel with a natural finish and includes a large 46mm piston for improved damping consistency. Its powder coat option provides enhanced corrosion resistance while the monotube layout reduces stress points inside the adapter.

• Steel construction for strength under thermal and mechanical loads
• 46mm piston for consistent internal damping performance
• Durable powder-coated finish available for superior corrosion protection
• Robotic welds and monotube design minimize internal weak points

How easy is installation and what comes in the box?

Installation is straightforward for anyone familiar with carburetor and intake work. The adapter ships ready to install with the required gaskets, and its dimensions and bolt pattern are designed to match common Edelbrock intake-pad layouts.

• Includes installation gaskets for both mating surfaces
• Pre-formed tube ends and monotube layout simplify alignment
• Designed to bolt directly between carburetor and intake when compatible
• Ideal as a drop-in replacement in most retrofit scenarios

Who is this for? The Edelbrock 2732 Carburetor Adapter suits mechanics, hot rodders and engine builders who need a dependable way to mate square-bore carburetors to Edelbrock spread-bore intakes or similar setups. If you’re swapping carburetors, repairing a worn adapter, or assembling a custom intake package, the 2732 offers a precision-built, leak-resistant bridge with included gaskets and production-grade welding for repeatable results.
