I'm installing a new cam soon and ordered the LS2 set. I was thinking about going with the double roller but I wanna know first if anyone has broken an LS2 chain. If noone's ever heard of this happening, I'll keep what I got.

 

I have only heard of one person, LS1GTO.com if I remember correctly, scared a lot of LS2 timing chain users when he posted. Not seen any others so there appears to be a good history. I also opened an 04 Vette this week for a cam, already had the LS2 chain in it from the factory which was a nice surprise, we compared it to my LS1 chain (replaced with a Katech chain) and the difference was very pronounced.

 

My friend is running the LS2 Timing chain from TSP In his 408ci cammed nitrous car for 6 months now and the car runs fine with 7500rpm and close to 600rwhp.

Good luck.
