I've not personally done the swap but I'll throw out a couple of things you should be aware of while making your decision.
1. The Downing Atlanta supercharger *may* not be available anymore. You'll need to call them and verify that they still have some if you think you want to go that way.
2. There's a member here named J!m who has literally written the book on engine swaps for these cars. Details in the thread below.
3. Welcome and good luck.
