That's good to know. I thought that if it had forged internals it would be able to withstand a lot of power. Didn't think the block would make that much of a difference.
what he says isnt ENTIRELY true,425rwhp does nothing as far as limitations and neither is xxlbs of boost( boost is just restriction).
its cylinder pressure that is the downfall, not hp, the rods are only made to support so much pressure, whenever you go over that pressure, u run the risk of screwing things up.
common misconception, but there are guys who have pushed stock internals to 600+rwhp.
