Default Stock internals max hp

How high can you go on the stock internals?Or how high has anyone got?

how about the pink pistons and rods on the 92-94 engines?

How high can you go on stock crank with forged rods and pistons?

yea Ive heard more problems with reving a stock bottom block to high and spining bearings than it going cause of to much horse power. I spun two rod bearings and rebuild my bottom block with a custom cam and ported heads.
