This is an original 1959-62 era Buick Nail Head V8 4bbl Rochester Carburetor. Pretty good looking condition, not stuck, moves good, looks to be a good core for rebuild-see photos. This came off of a Buick 401ci Nail Head V8 engine w/ a Wildcat 445 Air Cleaner on it. There is no tag, so I'm Not sure of exact years, models or engine sizes this may fit. Please check my other auctions.
