To my knowledge ls1, ls2, 6.0, 5.3, and maybe the 4.8 all have the same crankshaft. Unless your wanting to spend extra money or stroke it no reason to replace crank.

Stock crank will hold 1000rwhp without issue.

Pretty much your best option. Another option for a piston would be diamond but weisco seem to be the best ready to install pistons.

Wiseco and Diamond are both good pistons but neither one of them makes a stock bore piston. You will have to get the block machined to accept the larger piston. This only applies if you are doing the building of the shortblock yourself. Mahle is the only one I've found to make a stock bore forged piston.

They're better than the stockers but are lacking alittle compared to Wiseco and Diamond.
