now the LS2 and L76 might share the same block, since they are both 6.0L engines

Are you sure about that? Are all those listed not 4th Generation Chevy Small blocks? Displacement does not matter - since the 7.0 L LS7 shares the same block with the LS2, and all its cousins listed here, too. (Or so I thought)
I'm pretty sure that the LS2, LS3, LS4, LS7, LS9, LSA, L76 all share the same Gen IV block, to name a few. The rotating assemblies (displacement), bore (displacement), and heads, etc. Are a different story.
