All stock and in good running order with some extras (like radiator, accessories, wiring (if any), etc.) I'd start it off at $500 around here in the north east. Location plays a big roll with how much stuff gets sold for. look on craiglist as other makes or BB motor and trannies and go from there.

 

I agree local is major factor. Too keep in mind alot of the motor home stuff is different too, Like the trans, the mount is different from a pass, car, so unless a truck guy need s it thats a hard sell , then the heads are different for the cooling syst. the only things a car guyll be interested in is the short block.
