The Holley 1-inch Carburetor Spacer 2300 Flange (part number 17-72) is a precision intake manifold spacer designed for builders and enthusiasts working with Holley 2300 series carburetors. This component is essential for improving fuel distribution, reducing heat soak, and optimizing engine performance on various builds, including street, strip, and competition applications.
This 1-inch spacer maintains the 2300 flange interface, ensuring direct bolt-on compatibility without the need for adapter plates or modifications. The spacer's design increases plenum volume and improves fuel atomization by allowing cooler, denser air to travel through the carburetor bore more evenly. By creating thermal standoff between the hot intake manifold and the fuel bowl, it reduces fuel percolation and vapor lock, which is particularly beneficial during lean jetting or extended full-throttle sessions.
Mechanics and engine builders installing Holley 2300 carburetors on small-block Chevys, Fords, and other platforms will experience enhanced throttle response and cleaner low-end transitions once this spacer is mounted. The lightweight aluminum construction minimizes parasitic weight while maintaining structural rigidity, making it suitable for both street and racing applications.
