Dual feed 427 oil filter housing usually found on 427 cars to feed gauge pod and oil pressure switch. Of course you knew that.
I haven't tried to clean it up so it will look better when you're done with it. It does have a rub mark along one of the mounting flange edges. It looks like somebody knicked it with a wrench. There is a small divot taken out of the flange. Does not impact functionality and is repairable with some aluminum rod or however you do that. I just wanted you to know. Nice rare piece.
