Dont worry about it, it is good as new. Look how many times many guys rebuild their engines.

Actually it's hardly any difference between the LS1 and LS6 blocks. Not really "cool" since although there is theoretical (never yet shown in performance) improvement in bay to bay breathing, it also means less structural integrity. It's a trade off at best. Not good, but not bad. It just IS.

LS6 Blocks have far better coolant and oiling gallies. a Bit more aluminum around the back side of the block, #7 & #8
What this means, is the #7 and #8 cylinders do not fail as in the LS1 blocks have or can. When an LS1 fails under high strees, it is most likely poor oiling around #7 or poor cooling around #8
However, unless your running 3000 + RPMS 20 to 60 mins at a time several times a weekend, and no street driving, ( road racing) it does not matter.
More HP is not likely.
That is why the LS6 block was developed over the LS1 block.

Everyone has a theory. Especially those with an LS6 block. I actually believe (through research) the intake to be the cause of the #7 cylinder going bad. Oh and that's what most of the world accepts as the reason as well.

Does this mean it is an LS6 Block with LS1 Heads?
