LS2 chain - what difference? Why is the LS2 chain recommended over an LS1 chain, or is it just that they don't make the LS1 chains any more? If I buy one, is it just a case of swapping the chains over, or would I have to change/modify anything else?

That's great... is there a Howto somewhere that will tell me what to do - LS1Howto.com shows how to get to a stage that exposes the timing chain (with the oil pump swap) but not how to remove the chain itself, or is it pretty straightforward?

when you remove the 3 bolts holding the upper gear to the cam, you can lower the gear down, and then unhook the chain.
assuming the oilpump is off, then you can just slide it forward, and off the crank. install is the reverse.... just remember to lineup the dots..

That's great, thanks - I suppose I put the crank bolt back in to turn the engine, do I? It looks as if I'd have to completely remove the oil pump to swap the chain - is that correct? That's a PITA, but if it stops my engine eating itself, then que sera sera...

Putting a new chain on worn sprockets is not the best situation.
I know lots of people do it and all seems well, but they wear together as a set and should be replaced as a set IMO.
