Do I need a different chain for this cam???
Ok my cam, dual springs, rods ... cam in yesterday, simply a hing of beauty. I have a decent size cam 232/238 620/612 112+4. I seen somewhere where it says if you have more than +2 you should up grade your chain. Do I have to do this with my LS2? and if so, where can I buy a good one? what brand would you guys go with? and what cost am I lookiing at?

You will get a mixed bag of answers on this, but in my research I bought the Katech C5R racing chain. I read that they have never broken one in the history of their racing program. Also, at no other time will you have better access to the chain then during a cam swap. It was worth the peace of mind to me, but subfloor has tested his cars mechanical limits more than most of us and he says that he hasn't had problems. I think I remember that breaking timing chains are more of a concern in an M6, not so much in autos.

My oem chain was fine. But, I purchased/installed the C5R chain for cheap insurance since I was R&R the cam anyways.

For the $40 cost ($54 suggested) a replacement GM chain is cheap money. +4 is a lot of advance and more advance than is likely necessary to take up the slack in your chain. +2 is generally about right in my book. Do you have plans on degreeing it to see if that +4 was necessary?

Hinson motorsports has the C5-R chain. It costs about 3x more than the GM replacement, but it was worth the peace of mind to me. Especially if Corvette racing has had success with them. I have never heard or read a single bad comment about this chain.

Good looking cam grind, how many miles do you have on your car right now?
I had right at 40K miles when I did the swap so I went with the C5R chain as the cam I have is a touch more aggressive than yours and wanted the insurance as mentioned by taken19.
If you don't replace it while your that deep and something happens down the road you will kick yourself as the damage from a broken chain is a hell of allot more than $150. That was my logic.
