Stop in for a cup of coffee

I have a question for you x-spurts....The perimeter officer (the guy that rides around in a truck watching the outside fence) stopped me as I was leaving and asked me if I would be interested in a 340. It is a 72 has crank, pistons, no heads. He bought it in 1996 for $150. No idea what condition it is in. He was told it was running when torn down. What's it worth? My Challenger is a 72...that would be good in there but I bet there would be a lot to get it complete.
