Found this site while looking for a calc to determine a safe engine rpm limit. Lots of helpful calcs, many above my level of technical knowledge.

<-- added to favorites... i may have to go through them all later, there was quite a list.

oh, and you're running custom pistons right? the manufacturer should be able to give a good idea of how many FPM they can handle...

Nope, production forged pistons for the LS1 (in a custom application I guess).

ahh.... well, i know cheap cast pistons from the 80s stood up to ~3500 FPM for quite some time.

and considering that LS1s run to at least 7K with no issues with a 3.62" stroke, that should be a good guide. i thought i remember reading GM revved them to 8K, but didn't make enough power past 7 to justify raising the redline?
