These are all factory pulleys from a 67 327 with a/c and air injection. I've checked the part numbers. Every groove has a belt on it. So my thinking is this is how gm did it in 67 or there was another shroud . This is a picture of the only other 67 I know of that had air injection on a 327 and it does not have a shroud on it and I can't tell if it has aclutch fan ot not.
