No you can not put a 2bbl carb on a bbl intake and get any good results. Always turn your carb over and make sure what you have matches your intake, on any carb or intake combination. The ports under your carb whether it be 2bll or 4bbl should be slightly smaller than your intake so your butterflies will open at WOT (wide open throttle). Or it just will not work properly. Make sure carb gasket does not interfere with operation of butterflies opening
