The block # on drivers side is 2552929 and the # behind the flexplate on passenger side is D045.
The engine has a mechanical injection pump with no turbo

The julian (when it was cast) date will be on the opposite side from the 929 #

With that # we can tell when it was made.

This is a 6.5 block most likely

Does it have a one piece rear main seal ???
