That is true from all the threads on tech and everything. It was the ones that were made later because they ran out of the LS1 block so they used the LS6 block, its a different shade of gray and has a different part number on the back.

Then why everywhere on tech does everyone ask about checking to see if they have a LS6 block? Aren't the oil passages different or something to that extent. Thats what I always read on here.

Yeah thats what it was, but I heard there is less structural rigidity because of that, therefore the LS1 block can take a bit more abuse if you really push them, could be wrong though but I'm pretty sure I remember reading that somewhere here on tech.
