It apparently has somwthing to do with oil pressure and oil starvation....

what causes ls2 to spin rod bearing - LS1TECH

Maybe upgrade the oil pump and/or port it for better flow...

I've also heard that ls1-2's get valve float which sometimes sounds like that also

Ls2 with built engines almost always have upgraded or modded oil pumps....

stock valve springs are the weekness of LS1/2 motors, but are cheap and easy to fix
