This is a response I replied to someone else with:
"It is doable, but it is a lot of work. This isn't just some swap where you pull the car into the garage on Friday after work and roll it out late Sunday night with a new engine. There are a lot of different little parts that you would never consider. On top of the obvious things like: rearend, transmission, springs, radiator, rad fan, intercooler, fuel pump, complete SC engine long block. Other things different are the throttle cables (not sure about the trans TV cable), the A/C system might as well be off a completely different vehicle as I don't think any of the parts will be useful from the n/a to the SC. Alternator is different as well. Driver's side motor mount is slightly different as well. This does not even get into the wiring harness or computer. Basically a whole ton of stuff. For best results, I would suggest getting a wrecked SC and swap parts directly from that vehicle onto yours. Otherwise you will be endlessly searching for hard/difficult to find parts to complete the swap. Not saying it can't be done, but you had better do your homework before you start."
