Default 1981 - Vin on Engine Stamped Over?

I found the engine stamp on my 1981 vette, and was able to see that the suffix code is ZDD, which from what I read means it is a 1981 motor with a manual trans. However, where the vin number is supposed to be under that suffix code, it looks like it was stamped or marked over with just slashes - "//////////"

Is this common? Does anyone know what this means?

Thanks!

Hi,
While engine plant and St.Louis 're-stamps' and 'grind-outs' are not common they are certainly seen.
As 69 said, a photo of the pad may give some indication as to what may have happened, where, and when.
The same type of stamp irregularities is seen on transmission cases too.
Regards,
Alan
