Can anyone help ID this engine?

Does the '60 slant have ID stamps in the same places as others? If so, on mine they appear to be absent:



And there is no sign of anything on that little bit either . . .

Block casting is 2128418 - 4


Thanks a lot guys,
60 Ply

Check the block behind the water pump on your '60 engine.
