With-in a couple of days I'm sure. Only took like three-four days to build back in the day.
Good opportunity to link to a thread which had pictures of the factory process!

Since the engine/transmission were installed as a single unit in the frame, then I would have to assume that they were stamped with the VIN at the same time. May be wrong but it seems logical.

Notice the 2nd to last digit of the VIN derivative engine stamp, the #7 is slightly raised
Same #7 raised on the VIN deriviative transmission stamp
Being aluminum, the impressions in the transmission case are slightly fatter than those done in the cast iron engine block

Found this photo of a stamp gang at St. Louis courtesy of John Hinckley on the NCRS board. The transmission case was stamped immediately after being bolted to the engine. This thread should pretty much put to rest any further questions about alignment of the individual characters. Notice how crooked they are in this particular gang, and how they are held in place with a spring clip. Lots of room for movement.

For sure they were stamped at the same time. Because the Vin derivative on my block and my transmission were stamped with the same mistake.The last 2 of my vin ends in 75 but my trans and engine both have 76 stamped in too them.

I'll be sharing a few adult bevvies with him at our spot in the vendors area at Old Town for the January NCRS meet. I'll see what I can do.
