63 Futura 'Vert, It Begins With Many Questions

[Millennial Falcon]

New to the forums and Falcon ownership.
I always admired from afar, but now I am the proud owner of a 63 Futura convertible with bucket seats and the 170 special.
I told myself that I would not buy a project car. But then, ifyou’re like me, you see what you can afford and what you can find locally and you realize quickly that you’re not getting a show car.
I feel good about the purchase so far. I started out telling myself I wanted to keep this car all original so I could go to shows and stand a chance at placing. Now I feel like I just want it to stay complete, run well,and drive safely.
My father in-law saw the car, and being a big horsepower mustang guy, he of course wants me to do a V8 swap. After doing some research, I don't feel like my chances are very good of locating all the parts needed for that swap, at least not very affordably. Am I wrong in this assumption? I read that the 63-1/2 made the V8 swap easier, Is there a method for determining if a Falcon is a 63 or a 63-1/2?
Another option is a 200 inline from a 68 mustang that I could possibly rebuild. I have no information on the age and use of this motor, I also will likely never have the money to do the Australian aluminum head. Would this swap be worth doing?
Also, I am struggling to find anyone that has done the Wilwood 4-lug disc brake kit on a falcon, anyone heard anything about it? Am I nuts for wanting to keep the 4-lug setup and just put on some Scott Drake 15x6 wheels? I know everyone will say to go 5-lug and be happy with the better selection of wheels, but it seems like a bigger undertaking than I really want to get into. (remember, I’m still telling myself this is not a project car!)
