if they are less then helpful, just look at tables get resistors for each value and try em all, i think if u get it wrong you have to wait 15 min or something, so not the end of the world but still a pain

So, I take it that you haven't picked up the car yet?

You'll need to have someone registered with GM as a locksmith to look up the chip code. They will have to do the same with the key code. It could cost you $50+ once you pay for the chip lookup, key code lookup, and have a new key made.

yea i bought it. 2 years ago as a roller just put the engine in it

Oh - then you have other issues. A VIN lookup may not help you unless you have the same PCM that came from the factory. Did your engine come with a new PCM?

put a ls1 in it, took the vats out of the pcm,this is the 3rd one have done,1st ignition put in one.

Cool - So if you had the VATS disabled in the PCM, then you shouldn't need a resistor chip for the ignition, right?

If you don't have the keys, your best bet is to pick up a new ignition cylinder at the autoparts store and install it. (If you have the tools, it will probably be less expensive than having a dealer look up the key sequence for you.)
