I have heard the stock bottom end is good for around 400-430hp, after that, stronger internals are required.This is according to the big cheese at TPIS.

I'm putting close to 500hp through my naturally aspirated L98 (flywheel hp). Of course, I'm not saying that everyone can do this ... but, I'm living proof that you can do it.
