The block was cast on September 12, 1968 (I 12 , and assembled on September 18th. The "I" character in the pad stamping was almost always used instead of the "1" number character.

Block casting date:

I = September
12 = day of the month
8 = 1968

Pad Stamping:

V = Flint V-8 Engine plant
09 = September
18 = day of the month
DZ = Usage suffix (Z/28 302)
