1969 engine VIN discussion

The BH letters are not a factory stamp. It is a 69 block that someone restamped. Could be the number of the car they had it in. Kim

I would disagree. The factory stamps were hand hammered. Everytime the stamp was hit it makes another impression. I have seen a lot that look like this. I see at least a double imprint on allmost all of the characters.
