LS-1 and LS-6 Blocks

For yall guru's with the LS's, how much horsepower can a stock bottom end take on the LS-1 and the LS-6? I'm asking because if I upgrade from what I have now, I know i'll be pushing the limit. Gimme some good news fellas!!!!

On a few c5 vettes I ve seen a little over 600rwhp last for a while but ive seen them go at 500rwhp. It all depends on the tune. Your tuner will play the biggest role plus detnation. Those two r going to b the big things 2 watch for.

The cranks can take around 1000. It is the rod bolts and the pistons that will get you.

We've done a lot of ProCharged LS1/2/6s in the 515-530 rwhp range on 93 octane. Many of these vehicles are not just everyday drivers, but some customer's only car. Garrett114 is right, tuning is key.
