Cool project!
Just get her safe, Flinstone free and driveable. I made the mistake a few times over the years by doing too much to a car and not enjoying it. Nothing wrong with a updated safe chassis, crate motor with a 700r4, moderate gears good paint. Driving it it sure beats watching everyone else as you save $$$ waiting to buy that special part because its a snowball down a big hill you get one special part you want it all and it takes forever to finish. But who am I to talk its your show.
You might appreciate this. the car was a project my brother and I were working on now it is all his. its was a 72' Nova.
