yep. there is a guy on turbomustangs.com who ran 612rwhp on a stock block for over 3 years with no problems. sold the motor in 1 piece. i made about 550fwhp on my stock block with no damage to the block at all. then the pistons died

302's are suprisingly resiliant, at least when treated right. Even the stock crankshafts can take a wicked beating and keep in one piece and straight. For that kinda power I'd personally run better rods with floating pins and some good forged pistons(I am actually), it'll make me feel better when I get on it, but also if you pick good parts and you use lighter rods/pistons you're taking some inertial load off the crank, and hence, off the block. I've heard of a few people who split the blocks(uncommon though), don't know anyone who lost a crank, and the only folks I know who threw rods, broke pistons or ripped up a valve train were because they were stupid, used cheap crap or abused the parts beyond their limit
