My husband owns a 1969 coupe, with a 427 big block, that we are trying to restore. Our latest problem was a bad carburetor. We were talked into buying an edlebrock torker II manifold and an edlebrock 1407 carburetor (750cfm manual choke). This package was to fit under our big block hood (not L88) with no problem. It does, but when we try to put on the air filter, the hood won't close. We are about 1/2 inch too high. We need suggestions for an air filter that will fit this package and still let the hood close. Please help !
