So $95 for an actual GM production piece that was designed by GM, tested by GM, and made out of a material they approve for use in an engine is too much, when a one-off handmade piece made by some guy out of god knows what for use in a drift car, tested in ONE engine is worth $75? Oooook....

And I totally dissagree that GM makes a stuff and test it's, none of the car manufacturers actually test they engines in the long run, they design and make one, if there are any major faults, they recall the things or issue service bulletin with modiffied parts, but that's it. Testing is the waste of money.
Other thing is material, they use cheapest material available for application, to keep the costs down, nobody intrested in making engine parts that last forewer, because of aftersales, that's were they start earning some real money.
I would go for a delrin alternative, becouse of the propetties of it, it is allmost the best material for such application.

Dominic,
I would like to back up a bit and ask a couple of questions:
1) Why did you install a double row timing chain? The chains that Corvette Racing, Katech, etc. use are single row.
2) Was the engine equipped with a dry sump system?
3) If you did not have a dry sump system on the engine, what oil pump did you use?
Thanks, and good luck with your new project.

I was under impression, that the standart dampener is made for use with single row chain, so it is more narrow.

Katech has some nice stuff, but for what it costs it better be gold plated. Not bashing them, or gm or anyone else. But its a damn piece of plastic to keep slack out of a chain. Its not no complicated design, as long as the material is correct I dont see why it matters.

Hey Tomis GM actually tested LS engines for YEARS before releasing to the public, it's called research and development...they even ran some engines full throttle 24 hours a day for a month...and they survived, the LS platform is as strong is it is in the marketplace due to the many hours developing these engines, almost 16 years with minimal change which is most impressive...

Marysville WA, home of stonhenge. I'm in Portland, a stones throw away. 
Get it?.....
Looks like a good part. So quit bashing him.
Delrin is neat stuff. Slippery, reasonably easy to machine. I have built suspension bushings with it.
Dominic, nice idea. Would be neat if you machined a small grove in it to align the dots!
Myself, I used a Cloyes adj. setup and there was no slack in the chain. I'm sure there will be some after time, but nothing like the LS2 chain is brand new. My block is a 2000, I do not believe it was drilled.

Delrin is not the ideal choice for a timing chain dampener. Nylatron GSM or Nylon 4.6 (Stanyl) is a much better choice due to their heat, wear, and chemical resistance properties.
I went with an SLP double roller setup for my build and there was no noticeable slack, yet I have still heard of double rollers breaking in road course use.
