The 350 I purchased had a serial # sticker U621XXXX
Good old 409 washed the number off, so I removed the sticker.
There is no number stamped in the block...just shiny iron.

Do I correctly conclude that:
1. The short block/motor has been rebuilt by an engine rebuilder??
2. The block has been decked, which removed the original s/n ?

Are you looking at the back of the block behind the head?

Back there I found block # 10243880 along with date code A307 and identifiers 57LG
The serial # sticker was on the flat shelf of the block in front of the passenger side head.
