2 words. Donor car.
I base my following recommendations on the fact that you want a fully functional and comfortable daily drivable V8 non race type car.
The right way:
Engine, trans, rear end, springs, brakes, computer, wiring harness, fuel pump, engine accessory brackets, exhaust.
The wrong way:
Anything less than what was mentioned.
They way that you posted this question, it would seem that you are better off getting a V8 car the first time. There are still some good virginal or modified the way that you want cars for a good price in good shape.
