Are the prices for a used 87 300sdl negotiable or are they pretty firm. After one false start to procure my new/used motor I am just about ready. Including shipping I was quoted from $1800 to $3000 for this engine,including the bolt ons. Is this the right range, I know one board member purchased one for $1300. Would like to stay around the 150K range or less. Any advice is appreciated.
