How much is too much?

I need to know how much HP a stock block can handle before flying apart. Lets assume the rotating assembly is indestructable. It would be awesome if someone knew comparison numbers between stock main caps and modified.

i wouldnt go anymore than 400-450 HP at the flywheel with a 100% stock bottom end. Anything more than that and you're asking for trouble in my opinion. Sure, someone might be running more than 450 on a stock motor, but they are probably aware of the risks and know its not gonna last forever.
