[1950copper]

I've a 1993 Chevy S-10 pickup with extended cab.
Can't get too much for salvage.
Contemplating putting in a new motor.
Excellent mechanic is willing to rebuild so miles would be 0.
The body is in fair condition, no body damages, paint peeling, clean interior. Oh yeah, it has a camper shell with broken rear window.
My question: if I pay $2000 for the new motor how would I determine the truck's value?

Thanks for any help you can give.
