Hi Jeff,
Lines up perfectly. Car build date 02/21/69, block cast date 9B4 C Scratch.
Engine never rebuilt, crank still on original ford main bearing with 1 69 date stamp. All dates I believe line up perfectly on components other than water pump. All either A or B.
My first concerns was that someone stamped the numbers in to make it appear it was original. When I seen the C scratch I felt a lot better.
I do have lots of photos if it’s of interest.
Regards Greg
