The Moroso 2-barrel to 4-barrel Holley carburetor adapter is a 1-inch phenolic adapter that lets 2BBL carburetor bolt patterns convert to a 4BBL Holley 4150/4160 flange. It provides a phenolic conversion interface to adapt smaller two-barrel carburetors for use with 4-barrel Holley mounting provisions where a one-inch phenolic spacer-style adapter is needed.
