Almost all gp's knock from the factory, unless you have a freak. Don't buy a modded one.
Make sure it has a stock pulley. A good way to tell is if their is a hub on the snout spindle and the pulley is bolted to it. It should look like a pressed on type pulley measuring 3.8".
Make sure the car shift into 4th, should be around 45-48. 4th clutch is a known problem on 97-02 cars, later gm redesigned the clutch with a hardened one.
Check the LIM gaskets, your gonna have to pull off the cover, there is one screw on the top going into the top of the s/c, then you have to pull the oil cap and twist off the oil neck, then lift up and pull gently towards you. If they appear clean and silver, the were already replaced with the new aluminum designed ones. If its sludgy looking around the LIM and the gaskets appear black, those are the old plastic ones, they'll need replacement.
Listen for any abnormal sounds, these engines are a little noisy but, listen for anything out of the ordinary.
-oh, i just realized opp was looking at the car today, i wonder if he bought it...
