Blower plus Nitrous on stock internals?

Okay, I know this sounds like a bit of a stupid question, but I have considered running a centrifugal blower (most likely a ProCharger) on my car as well as a small dose of nitrous. I see the Zex kit and it's awefully tempting, but my main dilemma is the effects of nitrous. I have heard and seen the negative effects of nitrous and it makes me a little weary of it.

Now, since I am planning on building my car as a SEMA vehicle, I'd like for it to be a little over the top. So my question is this: can the stock 4.6 stand up to the power of the ProCharger and a 75-100 shot of nitrous? I hear a lot of people saying that 500rwhp is kind of the limit on the stock internals, and with nitrous, the car would be at about 530-550rwhp, but only in short bursts. What do you more educated folks recommend?

Going to forged internals would be ideal, but what's involved in doing it? I mean, I've had a forged rotating assembly put together for the big block in my Chevelle, but the engine itself is fairly low-tech. I have no experience with newer motors and computer controls. How involved would something like that be? I don't want the car in a shop for weeks and really don't have the time right now. Chances are, I will just go with the ProCharger. Everyone I have talked to so far at ProCharger says the new 4.6 is really strong and of the 5 test mules they beat on during testing, none of them had any engine problems whatsoever. I'll be sure to sleep on it though.
