Can you put a 2 barrel carburetor on a 4 barrel intake?
Moroso has a good one, it is for adapting a holley 2 barrel to a 4 barrel intake, the recess is cut out in front for the holley and will not be used. To clear the power valve of the 2 barrel motorcraft you will have to use the thick carb gasket and it works great.
