What damage can stem from a snapped timing chain?

A guy that lives in my city is considering ixing his 96 z28 with a snapped timing chain and then trading it for my car. I told him I would not trade into a car that wasnt running. He said that perhaps he had piston and valve damage. Is there anything els I should be asking about besides the piston and valve damage? Also do you think its worth it to trade a 96 LT1 with 40 k mileage and really nice paint and rims and such for a 98 firebird 3.8? Considering it but not sure if its worth while. His is modde too =) got a hotcam and some other goodies.

No, unless you have the cash to fork over for a new engine, labor, downtime, etc.... Yes, the engine may be rebuildable, but you must assume the worst.

so most likely its not worth it to trade my 98 55k mileage firebird with no problems, for a z28 with issues. Ill go look around at the dealerships then hehe.
