running or not?

ive decided to sell the truck i would never sell. i think ive owned it close to 10 years...i dont really remember. my youngest son took it for a bit but decided it was too costly to drive. ok here is my question...im keeping the motor, i have close to three grand into it (the one in pic isnt it) how much more would i get for the truck if i put a runner 350 in it vs just selling it minus motor and just selling it as a roller? here is an old pic of it but its basically the same truck except now it has bfg 33 1250 15's...this isnt one of those "how much do you think this truck is worth?" questions, just how much more as driveable.
