This Moroso adapter converts 2-barrel carburetor flange spacing to fit 4150/4160 bolt patterns, using a machined 3/4-inch billet aluminum body. It lets older 2BBL carburetors be mounted to common square-bore intake flanges while maintaining a compact stack height. The billet construction provides corrosion resistance and a serviceable, accurate adapter for custom carburetion projects and rebuilds.
