Others can answer better due to hands-on experience...but here goes.
1st, I assume you mean bolt-on parts for this...probably 480-500.
2nd, Most stock engines can accept 7-8lbs of boost safely. At a stock 400hp, this translates into roughly 550hp-600hp.
3rd, 500-600, I'd imagine. But you're gonna shell out a lot of dough the higher your hp goal is going this route.
4th...virtually limitless. But the stock LS3 engine block is rated up to 1000hp, if my memory is correct. Any more than that and your engine is gonna explode.
