There is a pad at the front of the block at cylinder head gasket level on the passenger side that will have two sets of number / letters stamped into it.

The larger set is the assembly plant ID code and application ID code and the smaller set is the partial VIN number from the vehicle it came out of.

There is a set of numbers cast into the top of the bell housing flange on the driver side that will tell you what the block is and what year range it was produced. Opposite side of the bell housing flange is the casting date. A single letter and a couple numbers. Month A is January and so on with the double digit day of the month and a single digit year.
