Engine VIN number stamping’s can you show me examples?

The engine 'serial number' on a small block in on the drivers side front face of the block. It notes displacement, fuel type, date of final assembly, etc.

If you meant the 'partial VIN', it will be on the passenger side of the block down low, right above the oil pan rail.

Posting pictures of what you can see will only help others answer your question better.
