Default LS2 and the old small block ...

Can any of you real gear heads tell me if there is any of the old chevy small block legacy design built into the LS2? I doubt it ... but I heard somewhere that the basic block may have some design commonality with the old mouse motor.

Try Google -- chevy small block history --

Some very informative stuff. Basic answer is yes, but the evolution of the motor makes it more complex than yes or no.

The bore centers are the same. Everything else has been at least tweaked. The most obvious difference is that the block is aluminum, of course. That dictated a number of detail changes, such as the 6 bolt main caps, sleeves, etc.
