Here is my 2 cents: I have a 64 Futura Convertible that started life as a 144 cuin fordamatic. It has been converted to a 347 Stroker with WC T5, Currie 4:11 rearend, all wheel disc brakes and an Omni R & P steering. Now you may not want to have to go that route but it sure changed the life of the Falcon. The stock 6 cyl springs are still in the car, I even cut a loop out to get the look I wanted. I also did a friends 63 Futura Convertible which was a 170 cuin and we converted his to a V8 and boy is he tickled pink. Now depending on how mechanically inclined you are this could be a good learning tool and a great father/son project for you. The weblink that 1bad6t gave is a very good start for you. This is a bolt in project once the right parts are had, but one that will not be an overnighter but a fun one at that. Only you can decide what you want as this is your brain child. There are alot of experts in this forum that can get you on the right track and point you in the right direction but in the end it is your project. The V8 swap is not hard at all but will take some searching for the right parts. Your donator car is a good start and yes alot of the major parts will work but they and your Falcon will need to be messaged to fit. Good luck.
