I am getting ready to sell my 87 Laredo. I have a spare engine that I was working on building up to got into it when it was done. Would I be better off trying to sell them as a set or trying to sell them seperate? The engine in the Jeep currently runs fine but has around 130,000 miles on it. I have a rebuild kit for the spare engine and it has got the machining done already plus some upgrade parts. Thanks in advace for the input guys.
