Greetings all. I am beginning the process of building a street 355. I've got a donor block, and I'd like to know its origin. Here's some pics of the casting # and the ID #. From the V1203TKT I understand that the V means it was cast in the Flint plant and 1203 means Dec 3rd. And from the TKT suffix means that it's a 350 from either '74, '78, or '80 and was originally for a pickup. Furthermore, the casting # 14010207 confirms that it's a 350 from 1980, and that it has 4 bolts on the main caps. My question is:
What does the stamping on the second row of the ID plate on the front of the block mean?
