The general consensus is that over 550whp, you're playing with fire. There hasn't been too many people who have popped motors (and all of the ones I can think of offhand were Stillen kits), but not too many people are pushing the stock block like you are. Sam at GTM told me 500-550 was safe, over that cylinder pressure starts to get iffy and you run the risk of a bent rod.
