I use single piston 74 calipers on my 11 3/4 with EBC red pads and 11 x 2 1/2 drums with good shoes on the back. That car stops on a dime, no fade. I live at the top of a long hill and have never driven a car with brakes that good. The larger rotors really help and good pads or use Viper rotors. I rebuilt the front end, Firm Feel steering box and reinforced Kframe and brake upgrade before the new motor went in. It's not cheap.
