I'm swallowing my pride and posting a third consecutive question:

How do you determine the year of the engine if you don't have the VIN?

From what I understand, the last 9 or so characters in the VIN tell you what year the engine was made but...it's just an engine.

There are some numbers on the block and head but I can't seem to find how they relate to the engine year. Maybe I'm just stupid.

Any suggestions would be appreciated.

Thanks!
