First off, I would like to know how hard it would be to swap an 86 or 87 engine into an 81 sport coupe? The 81 was setting for around 10 years and the motor is shot and half apart. What parts I can use from the 81 SportCoupe? I bought the car complete for $300, so I figured I would fix it up. If anyone has had any experience in this, especially for the wiring, I would gladly take any suggesstions.
