25% in 02 came with the LS6 block. You have to use a mirror, and look on the drivers side rear deck just below the head. I don't know the full # but the first four for an LS6 are 1256 and LS1 are 1255.

BTW I looked for hours for that sticky the other day and couldn't find it...

Did find out mine is an LS6

Just look for the bullseye on the water pump pad on the passenger side of the block, if it has it, it is LS1, if it doesn't, it is an LS6 block.

I think what you are talking about is either a 5.7 or a 6.0 block. What made the LS6 different from the LS1 was the cam, lifters, heads and intake manifold. The LS6 was and LS1 with a different upper end and after 2002 the intake manifold was the same.
