I did a conversion on my 71 Road Runner with all factory parts, and everything just bolted on like it was, well, factory. I can tell a big difference in fade resistance. RRs had 11 inch heavy duty drums which are powerful, but one good hard stop, and that's it.
That was my biggest issue, brake fade! I learned to push, letoff, push, let off with drums on my Cuda.
I spent a little more money and did the aluminum hub and aluminum caliper Wilwood Pro Street kit on my '63 Dodge. Vented (but not drilled) rotors. The car stops from 121mph runs in the 1/4 mile easily and consistently. It was a very easy kit to install on my existing drum brake spindles and took a LOT of weight off the car!
