I'm not a hot rodder by nature, but I did build a 56 resto-rod. Throughout the project the main goal was to make sure it could be undone by the next caretaker if wanted. To me, disc brakes, dual pot MC and gears are pretty minor and would add to the driving safety without detracting from it's "originality"...the average person would never know unless you told them.
Bottom line is it's yours, so build it the way you'll enjoy it.
