1966-70 GM 427 w/AC. Bought years ago as NOS but had no sticker or tag so won't swear to it, although in perfect condition, cleaned and reprainted due to parts dep't shelf rash, no nicks or scratches or evidence was ever mounted, round head rivets and only one balance button (have seen as many as three). We put these on overheating big blocks when they were new. It was the cure. Pics by PM. $350.
