How much for an '86 SWB Silverado

[crawdad]

Hey guys, it has been many years since I owned one of these trucks and I was looking for some help in determining the value of a 1986 Chevy SWB, Silverado. It belongs to my nephew and has been setting up for years. He removed the motor from it with plans to install a souped up motor and never got around to it. There was really nothing wrong with the motor that came out of it. The body is straight as an arrow with absolutely no dings or dents in it. Has the original white paint which is showing some surface rust in several areas, but is solid metal.
He wants to get 2500 for it the way it is, but I'm not sure if I want to go that much considering.
I would really appreciate it if some of you could give some idea what it might be worth.
