Questions:
Anyone know what sort of fitment issues we might have?
What's a good source for a used take out engine (he's in Raleigh, NC)?
What parts do we want to ensure come with the take out engine? Everything on the engine like accessories, wiring harness, MAF sensor, etc. Also try to get the pedal and control module from the interior along with the harnesses there.
Do we want use the factory ECM, or some other? I like the factory PCM. It's more than capable for your needs.
Do we need to have the harness reworked? ECM? PCM will need to be tuned slightly even if you leave the engine stock. Harness might need to be reworked depending on where you mount it, how you route the wires, and if the wires will reach their destination.

Answered what I could in your quote. There's plenty out there to make this happen so don't be afraid to jump right in.
The Roadster Shops build thread on the Biscayne may help answer some more fitment questions
