4.3 casting number decode

I have a 4.3 engine that I am trying to determine the year of. All of my searching has left that question unanswered. The number on the shelf in front of the engine is T0513UDs and the casting number at the rear of the engine is 1409999014. Any help is always appreciated.

Try this article from enginebuildersmag. They have a lot of casting numbers on blocks and heads.
