Despite the paper work my Monaro came with and the work I have done since, I have no true histroy about the timing chain, it's age or if it was ever replaced. My question is when do you typically replace them? How hard are they to change? and is it worth upgrading the timing chain and sprocket to an uprated one as I have noticed a few options out there.

It isnt really a service item. Normally they're very reliable, aside from the other thread where the tensioner has failed, which is a known weakness for the models that use that design.

While you're in there yes you could uprate, replace, and whilst there time to change the camshaft.

I've heard that the LS2 timing chain is much better than the LS1 version. A few LS1 guys in the states seem to upgrade to the LS2 chain, so yours should be good for a while yet.

LS1/2 would be pretty much the same.

There are fancy versions available for all models, dozens of aftermarket options etc too. But for most part, they just dont give any trouble anyway, other than the LS3 tensioner pictured in the other thread.

The uprated stuff is more for when you're into big cams and valvetrain, running much higher rpm's etc

Certainly if delving in there by all means upgrade, but the chances of a standard setup failing is pretty low, and no guarantee that an uprated part wouldnt fail either.

I did this, and added a LS2 damper on an adapter bracket whilst in there too. Also did the oil pump and other bits, all of whilst was probably unnecessary...

Added an LS2 timing chain to mine when it was done also. Not sure it was really necessary but had it done anyway.
