HEY BEET: I have a 38 Lafayette strret rod running Mustang II and Buick rear end. I have had to convert front to 11 inch disc because stock 9 inch burned up. Still running drum in back. Car weights about 3700 LBS and it takes all you got to stop with manual system. Your car looks close to mine in body style so it will probably be about same weight. Power brakes would be a REAL plus

and a big safety feature. I attended a brake seminar at Goodguy"s and speaker pointed out most rodders build a lot of " GO" but not much " STOP" Give it your best....DAVE
