PROM ID #'s - confused

What does the second # mean in the FAQ section after the BCC 4 letter and 4 number code? I n the case below, what does the 16068672 refer to?

I have prom that says Delco ABWT 8674, so i am assuming it is an 87 350 and no chance it is an 88 350? Not sure what that other number means though as it is nowhere on any of the chips.

87

5.7-8

A/Trans (MD8), Fed, 3.27(GW6)

16068672

8674ABWT


thanks.

It is the GM part number.

ABWT is an '87 L98, federal, auto, w/3.27 rear ratio.
