LS2 OE block max HP..?
I want to build a LS2 427 twin turbo. I've seen some LSx blocks make well over 1000hp without any issues. Assuming the engine tune is mild for street use only do you think I will be safe with a stock/OE 364Cu/In LS2 block out of a 07' Corvette?

I see the LS1's start to crack in the 800 range. I wouldn't dare go 1000 on an aluminum block, and the extra bore size on the LS2 makes it even weaker. Get an LSx block if you want to make that kind of power.
A buddy of mine built 2 turbo LS1's in a row and both times he cracked the block right in the middle. For the third build, he got a 5.3 iron block, did a partial fill, and punched it out to the LS1's 3.90 bore. He makes in the 800's and hasn't had an issue yet - same tune as before too.
