2000 LS1 block
the research i did says the first weak link in the stock rod bolts, good to about 400 ish whp and under 6k rpms. the next link are the pistons them selves and they seem to be able to handle 500-550 whp on a good tune.
The block will take a decent amount of abuse. More than likely you will find the limits of the head gaskets or other part before you actually have a problem due to a block failure.
