Carburetor Adapter Plate

You’ve got a squarebore carb and a spreadbore intake manifold

You’ve got a squarebore carb and a spreadbore intake manifold—no problem! A carburetor adapter fits between the bottom of the carb or throttle body and the top of the manifold, just like a carburetor spacer, making the combination work!

Summit Racing Equipment’s powerful website makes finding the right carb adapter simple. Just select your flange types and bolt patterns in the left-hand column, and you’ll narrow down your search results! Then you can find the material, height, and brand you want.
