You can make pretty good power on a stock LS1 w boost. They're pretty durable too. The weakest point are the pistons, particularly the ringlands. Often what blows them up is rings binding and poping off part of your ringlands.

If you haven't buttoned everything down yet, id take the pistons out and open up the ring gap a little. I don't remember what factory spec is, but if it's. .020 open them up to like .035 and you can push a stock motor to ~700+ with no worries as long as you have a proper tune.
