? about LS2 timing chain is the LS2 timing chain any different from the LS1? im almost 100% sure it is, but the reason im asking is because when i went to the parts departmetn to order one, they said that the chains are the same..... does anyone have an exact part # for the correct one?

The original LS1 part number was replaced with the LS2 part number as I understand it. If he looks it up, he probably only finds the new one. However, if you give him the original number he will probably see that it was superceded.

Absolutely NOT the same physically, probably the same part number (now) in GM's inventory.. Bottom line is, the LS2 chain has thicker end-plates, it's a beefier chain compared to what you have in the car now.. Do it. Order it w/ the LS2 part number if you have to. 
The ls2 chain is the current replacement part number for ls1, ls6 and ls2 engines. When you look up "timing chain" for a 2002 trans am, it will give you the ls2 part number. Like the picture shows, its thicker than the chain youll be taking out of the motor.

not the same physical chain at all. much beefier and stronger. wouldn't put another ls1 chain in my motor if i had the choice of putting the ls2 chain in instead.

otherwise i would be all over it! Just replace the oil pump with a new stock pump and ls2 chain. Either port it yourself or dont even bother porting. Shimming is optional as well. Its a hundred bucks for the added piece of mind of a new chain and oil pump.
i was planning on getting the ls2 chain to... now does that come with the gears? or do you use teh stock ones or what..... and what are those part numbers and how much should cost?
will it work with f13 and dual spring setup?
