Kurt, Can not say I know of a situation precisely matching your question, however, I have seen a number of blocks w/the Tonawanda assembly date and code stampings, and no evidence of a VIN ever being stamped on the block. These could have been warranty or over the counter engines or perhaps some were giveaways to racers. What else would the extra engines be that were not installed in cars? They certainly would not have been destroyed.
