I'd like to see a very detailed list of what all it would actually take to make this swap on a torsion bar car. I've considered selling my whole 500" motor and tranny turn key to go this route. Do these engines come turnkey?

I believe I'd need a new motor plate, tranny adapter and a 904 tranny and converter. Probably a set of custom headers. Oil pan?
What else?
