Possible? Why yes it is...
Worth the effort? Well, that may be another story. But you probably won't know that for sure until the project is said and done.
Here's what I highly recommend (that is, if a donor SC can't be had at your disposal... like sitting in your backyard so you can take every bolt and nut you may need)
- Complete SC engine and trans. And that's an SC AOD trans, not your N/A AOD.
- EEC from the interior plus that wiring harness that leads into the engine bay.
- Wiring schematics for your car and for the donor car since there will be some wiring changes (don't ask me what, I don't remember for sure)
- Rest of the drivetrain - Driveshaft, rear end, axles, etc. The rear end and axles are stronger and will handle the SC torque plus you'll have rear disc brakes as well.
- A few weeks free time, ambition to finish, and beer (optional really)
From what I remember, and hopefully the one who helped me can chime in, the swap itself is pretty straightforward. It's the wiring that may be a hang up. If the car has sentimental value, or you are just up for the challenge, I say go ahead with the swap. If you aren't attached the car, I say sell it and find a Super Coupe.
