LS2 Timing Chain identification/ dimensions Hey all,
In the middle of a cam swap, on my 2004 GTO with a build date of 08/2004. I forget the cutoff date...somewhere in 2004 all LS1's got the LS2 chain...or so I read on one of these forums.
Car only has 7,000 miles on it so I don't see the need to change the chain....assuming it is an LS2. I have seen the other posts...but without a side by side I am a little in the dark here.
Anyone know what the link thickness difference is? Or any other way to identify it?
Thanks

I'm thinking the only way is to measure it.. Do you have a set of calipers? If you do, I have my old stock LS1 chain on my bench (can't seem to throw anything away) and I can measure the link plate thickness; you can then compare to what you have..
As an alternative, check out the pics in this thread. https://ls1tech.com/forums/generation-iii-internal-engine/391404-about-ls2-timing-chain.html They are accurate enough for comparison purposes. The LS2 chain links are quite a bit thicker, you should see the difference.

using dial calipers, the link plate next to the roller is approx .071
tomorrow I will have the chain laying loose for a more accurate measurement but I think this is pretty close.
Thanks again.
