power brakes for 440 a body?

My recommendation is the large 11.75 rotors and toss the power booster. With the big rotors the pedal feel will be just fine with a manual master cylinder. Use the late model aluminum MC to drop weight and prevent corrosion. For a drag car you can drop another 20 lbs by hanging some Wilwood calipers on the 11.75 rotors. That gives you a very nice setup that is fairly lightweight but has the big rotors for plenty of thermal mass.

For road racing the best setup are 13 inch rotors with Viper calipers and 17 inch rims. No power booster needed with that setup.
