There isnt a damn thing wrong with an LS2 chain, people have made 1000rwhp with them, they must work atleast decently well. Ive had a rollmaster double roller and the comp adjustable in my Z and niether were any different than the LS2 chains Ive used. The double roller MAY have been a little tighter. In order to run the double I had to notch the back side of the front cover.

With that said, I wouldnt bother with it at your mileage.

 

No, I got the whole ls2 hd timing set.........not just a chain.........

 

The sprockets arent any different tooth wise than the other stock sets, just the LS2 cam sprocket has triggers on it for the cam position sensor.

 

and i think you have to grind the cover for the LS2 cam sproket to fit?

 

Have you ever measured how many degrees of backlash are in the LS2 chain vs. a decent chain? It's not that the LS2 chain is weak, it's sloppy. It actually "lashes" back and forth changing your valve timing. The GM chains are intentionally built with slop so robots can put the timing chain sets on. I wouldn't advise using one for any "serious" high performance engine build. If you're just dinking around with a cam only setup then use a cheap chain. I personally wouldn't though in any of my builds.

 

My point simply is people have made tons of power regardless of the slop you are complaining of, at some point its overkill. There are quite a few examples of people making over 700rwhp with a stock chain for sure, Id be willing to bet there are some even higher than that, I just havent taken the time to look.

You have your opinion, I have mine, Im no master mechanic but Ive been around a while and worked on a lot of peoples vehicles and IMO the LS2 chain is a nice upgrade if the stocker is getting up there in mileage.

Now for someone running a really aggressive high lift lobe with stout springs, Id just go straight to a double.
