I have been told that the stock crank is good for around 650hp.. If you get forged rods and pistons then your motor should be able to handle 600hp or more without worries. The stock 2000 bottom end is good to around 500hp. Many have ran more then 500hp out of there bottom end and have had no issues with it at all. When it comes to nitrous its all about the tune.
As far as breaking **** its an aluminum block. I broke a piston in my 3.8 V6 on nitrous and it damaged the hell out of the Cylinder wall so much that the block was scrap. Dont know what would have happened if it was an Aluminum motor.
