Ok im a little lost on what your asking?
A well sleeved block is a very strong base. For only 500rwhp both a stock ls1 and ls2 block can easily handle that
I have stock main caps holding about 1000hp many other people doing it too. But if you have the money get billet caps. but i would put money else where.

ok sorry i was a bit unclear i have a ls1 that is sleeved it has all those parts already so its a 402 i will be putting twin turbos on and i want 500rwkw not hp thats 670rwhp i was just trying to find out weather i should put all my internals in a ls2 block as my ls1 block is stuffed anyway also where can i buy a brand new ls2 block
ls1 vs ls2 In talking with Steve @ RED, I think he mentioned that a sleeved ls1 block was stronger due to not having the vent holes around the main caps. So probably a ls1 block would have a stronger main area.
Though he has sleeved ls2 blocks that are F I pushing 900 > hp.
