Carburetor Adapter - Std Flange to 4500

The Edelbrock Carburetor Adapter - Standard Flange to 4500 (SKU: EDE8716) is a precision-engineered intake manifold adapter designed to bridge legacy carburetor mounting flanges to modern 4500-series dominator carburetors. Built for serious engine builders and street performance enthusiasts, this adapter solves a common intake compatibility challenge when upgrading fuel delivery systems or swapping carburetors between different engine platforms. Whether you're restoring a classic muscle car or modernizing an older engine bay, this two-inch adapter allows you to retain existing manifold work while transitioning to superior fuel metering control.

Machined from aluminum and finished in natural bare metal, the adapter features an open square bore design that maintains optimal airflow and fuel distribution without restriction. The two-inch thickness provides structural rigidity while keeping overall engine compartment packaging compact, and the included gasket and hardware ensure a sealed, leak-free connection between manifold and carburetor. The adapter's square bore geometry is essential for carburetors that require full, unobstructed access to intake runners—critical for proper fuel atomization and engine response across the RPM band. At just 2.43 lbs, the adapter adds minimal weight while delivering the precision fit that separates amateur conversions from professional-grade engine work.

This adapter is ideal for engine builders transitioning from older carburetors to Dominator-series fuel delivery, particularly in vintage hot rod restorations, street performance builds, and vintage racing applications. Installation is straightforward—simply position the adapter between your existing standard flange manifold and the 4500 carburetor, apply the provided gasket, and secure with included hardware using standard fastener tools. Verify your manifold's bolt pattern matches the standard flange specification before purchase; this adapter is engineered specifically for that configuration and will not fit alternative bore styles or dominator-incompatible platforms.
