Max HP debate

Okay so I'm curious what the max HP/TQ everyone has pushed out of a factory block? Why do I ask? I want to push 600 out of a factory 360 block with W9 heads on it and I have had many people tell me both ways that it'll survive and that it won't, more so that it will survive. So debate, discuss your max HP etc and I'll put up a poll if it will survive. I plan to overkill prep that block and rotating assembly so that I has a very strong chance to survive in my opinion.
Stock stroke huh? Well, I don't have a clue. Best of luck.
