What's missing? 727 BB

Ther is a pad located on the drivers side just above the oil pan.

Might read something like this:

PK 4431552 9988 8395

First 2 [PK] is the plant in this case it is Kokomo
next 7 [4431552] is the part number, in this case A727
next 4 [9988] is the date code calculated on a 10000 year calendar search the web for a calculator :)
next 4 [8395] this is the production sequence.
I hope this helps.
