Ok people.

 Here's the word, directly from the Big book of Ford....  For those of you
that actually still have this tiny little aluminum bits afixed to your
engines....

Tag appears as such:  
351C   72-5
B7 KK621 SG 


First field is engine CID.  351 Cu Inches.

"C" is engine plant.  C=Cleveland, E or W= Windsor

Third field is model year. In this case 1972.

Fourth field is the Change level US.

Second line:
B7 here is the....I don't know....  just reallized I didn't write that
down.  AAACK!

KK621 is the engine code#. Here it is a 351-CJ
620 & 621= 351-CJ
625= 351 Special
These are the only codes listed for any "special" 351's.  The balance are
generic vanilla 351's, four barrel or two barrel.

Last field, SG, is the change level for Canada.

Not sure that all of these fields are maintained properly..... as it would
appear that there are some minor discrepancies......

The most important fields are the date and the engine codes.

I can decode more upon request, but the three codes mentioned should cover
most of the Pantera motors!!!!  And as Jack maintains, the tag doesn't
necessarily mean that you have what it sez.... it just means that at some
point in time, this tag was bolted to a particular engine config!!! Actual
casting dates and partnumbers reveal more....
