84 corvette brakes

Put 84 corvette front and rear supension under my 56 Stude wagon. Looking for some info on the type of master cyl and booster to use. Thought I would try to stay with the 84 vette stuff but seem to have a couple questions that need to be answered.
1) Will the factory Booster have enough PSI to stop a heavy steel car??

2) Does the master cyl have a built in proportioal valve? Can not find one on the corvette donner car.

3) am I better off going aftermarket with booster and MC and adding a prop. valve and will this work with the 84 system??

Any help is needed. Anyone out there who has used any of these aftermarket boosters and MC? Dual dia. Single????? Help

I don't know that much about 84 vetts but as far as stoping your car, it will stop the rotors the rest is up to God.
