Offenhauser 6269 Iron Duke Carb Adapter

Description The Offenhauser 6269 carburetor adapter is designed to bolt a large Holley 2300-series two-barrel carburetor (such as the 350 or 500 CFM) to the stock intake manifold of the 1980–83 GM Iron Duke 2.5L 4-cylinder engine. This adapter allows you to upgrade from the factory carburetor (often a Rochester Varajet or Dualjet) to a performance Holley 2-barrel model. It is commonly used in custom builds, performance upgrades, and applications like dirt track racing or hot rods using the Iron Duke engine.
