Need Help W/ I.D.

No on the date code. Go to the other side of the block (pass side) and look on the side toward the front behind the motor mount area and there you will find the date code cast into the block like the other side. It will look something like this
2-26-72. That is what your looking for. Disregard the date i pluged in. Those are just numbers that i woke up with this morning. May have been my old girlfriend. Lite on the top and HEAVY on the bottom LOL
