30psi should yeild way more than 600bhp, first off...
I personally wouldn't worry about either of those 2 components when it comes to power handling. The the cross bolted mains of the 3x00 block, that adds strength to the bottom end, and I have seen a couple Gen 1 blocks (1 with a stock bottom end) in excess of 400hp. As long as you use the correct hardware (ARP studs in particular), I don't think you have anything to worry about. You could look into getting the crank cyro-treated for added strength.

Block & Crank power handling
In short, does anyone know if a 3400 block and or a 2.8 crank would handle 600bhp @ roughly 30psi?
For the record, yes, I know what would be involved to get to that power level. It's a serious question.
The Gen III block is supposed to be stronger in critical areas than previous Gen's, and the 76mm stroke crank should be stronger than the 84mm stroke crank if there are no differences in material or manufacturing (verification needed on that end).
I haven't been able to find anyone who broke either one from too much power, so my assumption is that it's still an open-ended question (read: guessing).
Thanks for any insights.
