I will say I have fewer issues with the stamp now that the photo is clean and crisp and square.
The Vin Stamp exhibits many of the same characteristics as other early vin stamps at Norwood, characters/spacing.
IMHO the faint stamp looks like the gang was misloaded, it appears there are too few characters.
 Maybe? V9ODZ ?
I can make out the V and the round tops of two numbers before the faint DZ.

It looks like a restamp to me. I actually think the 04 is not part of the underlying stamp. When I get home I'll look at it on a big screen and post what I am referencing

I have documented one factory grind out on a '67 Z28 in which I knew and worked with the original owner back in the 1980s.  I have photos.

I know there will be some that won't agree, but based on what has been presented here and what I know...

I am 75 percent sure the block stampings are genuine.

Restamped - YES. But do you understand what a grind out and a FACTORY restamp are?

Grind outs have been discussed numerous times on various Corvette forums.  I can't remember which car it was, but there was a C2 Corvette recently on Bring A Trailer where it was discussed in the comments.  The Seller posted a weird letter from an alleged assembly line employee at the time talking about factory grind outs and how a different type of grinder was used on small blocks vs. big blocks.  Can't find the correct auction but will post the letter if I locate it.

Out of curiosity and lack of knowledge, where on the line would this grind out have taken place? When the engine left the assembly Plant, it only had the engine designation number on it and not the Vin correct? If the Vin was mis-stamped on the assembly line would they have not just ground out the Vin and re-stamped that?
