I'm certainly not the best person to ask considering my car isn't running yet but for the sake of conversation starting...I think the first "Y" in the road is determining how you want your induction system designed...ie carburetor, TB FI, or MPI. This will determine if buying a donor car is the easiest route vs. buying components individually. If you go carburetion, you'll end up with a lot of parts from the donor you likely won't need.
