Do ls motors have vin numbers on them?

I just went in the garage and checked my motor today and there is a number stamped where Scott has one on his block.

I live in the SF Bay Area......LS equipped cars are in high demand by the street hooligans in "Oaktown" lots of thefts around here....the Trailblazer SS must be easy to steal.....see them all the time on Copart auctions with drive train missing

My LS1 has a vin Laser etched on the flat side under the block.
