Especially if you need to run 15 inch wheels I really don't see the point in putting anything on it other than the stock 73 stuff. We had that set up on our 24 Hours of Lemons 67 Fury and never had a problem. It ran 10 races with that set up and we never had brake fade. It would out brake 90% of the cars on the track and we were about 4000 pounds with the big block in it. We got some very good race pads which obviously helped a lot.

We swapped on a set of 4 piston viper front calipers and saw almost no difference in ultimate braking power. The only reason we changed over was because the single piston caliper was cracking the pads after our first 24 hour race which scared us a little but if you are on the street that would not be a problem.
