they do, but i guess most guys dont run them when doing a upgrade... i called texas speed when my block was being machined and they said u dont need it unless your road racing. so i decided not to get it drilled for one

Hmmm, I can't say I'm familiar with that set-up, but it sucks that you're having problems. I, myself, wouldn't be comfortable with that much slack either. Anyway, good luck getting it sorted out!

ide say no way in hell chief. I used an LS2 chain on mine and my buddys LS1 cars when doing cam swaps and neither were that loose. Ide double check and make sure you actually got an LS2 chain, or perhaps it was mis packaged?

i ran into a similar problem on my build, only it was about 1/2 inch of slack with a katech c5-r chain. I ordered a cloyes hex-a-just single roller, it tightened it right up and it had a heavier duty chain than the c5-r. The chain was, or was very close to an IRL chain

In this situation, I would call Mike at Cloyes tomorrow. He can be reached at the performance tech line. I am thinking you need a new timing set to correct this. Even though you already have the LS2 timing chain, you can sell them fairly easy without losing a lot of money. If you want an absolutely bullet proof setup, use the Cloyes 3153-AL, which is the true IRL chain. Bring your wallet though. Lingenfelter is the only one I know that still has this set as they haven't been made in a few years. The IRL chain is made by Renold and was developed to solve the timing chain failures they were having with the Aurora engine in the Indy League. Here is a link to the timing set: Cloyes IRL Timing Set
You can also get the IRL chain separately. Cloyes actually has some left in stock but don't send them to their vendors. You can get the chain if you call. There is a good thread on this in the Gen IV section (the link above is one of my posts in that thread). I don't think the chain alone with solve your problem though, you should get a matched set.
One other note. If the center distance is wrong between the crank and the cam bearings, you may have issues with the block itself.

^^^^ I agree with Bob (Vettenuts) above. His posts and research led me to the Cloyes 3153-AL setup. I just installed it and boy....there is no slack in that setup....I was very surprised after reading all the loose chain posts!!
I would not run that setup as is....to me that is asking for trouble.
