Thanks for clarifying that difference. Perhaps your number 117 was the last of the 2015 numbered engines and then started over with a T and 001 for 2016. Just speculating and killing some time while waiting on production.
My car started production in 2015 and was supposed to be the last car completed in 2015. It got delayed by a few days...then came the Christmas break, and she finished on January 3rd or so, and got a 2016 VIN. I'm guessing you're right about my block number.
