Car Authentication help

There was a post in the last 2 years about warrantee blocks.

What is stamped on the front driver's side of the block right under the head. That will give you all the info on the engine. You could have a 69 cast block in a 68. My 67 has a 12/66 built engine as it was an early 67 (2/67) delivered car. Your fender tag should indicate a date around its build date.
