I suppose it could have been cast on 3rd shift and finished and stamped on 2nd shift (same day).

Here's one way to think about it. Many machinist, even back in the day, when blueprinting these things would re-hone cylinders while running hot water through the block to simulate temperatures during running conditions for more accurate machining since things expand and contract. Just a thought.
