I have been scanning ebay for engines getting ideas, and was wondering what the numbers are that tell if the block is an LS6 block. I had seen some post on this before but can't locate them now. Thanks for the help.

I think around mid '01 GM put LS6 blocks in all the F-bods and C5's. I am pretty confident all '02+ have them.
