Your engine MAY be a 37, but if it is, it will have blanking plates over where the pumps would mount at the front of the block. If no blanking plates, it is a 32-36 engine. Only the later 36 engines had insert bearings (ie not poured).
There are people on here far more expert than I on the earlier engines and they will probably be able to tell you exactly what you have. The first thing to check is the blanking plates, that will say whether 37 or not.
The V8-60 is a smaller unit and has (I think) 19 head studs. As yours has 21 studs, yours is not one of those.
