Boosters are interchangeable and make no difference on the brakes used. The MASTER will have to be for 4 wheel disc and incorporate a proportioning valve to adjust the flow to the rears to prevent lock up.

Your car shipped with an 11 inch vacuum booster if it had factory power brakes; not a nine inch booster. They use the smaller booster on the Camaro and the Nova because there is so little room under the hood for a big block Chevy to fit that they had to either move the engine or make the booster smaller. A smaller nine inch booster doesn't work as well as an eleven will. If you have an aftermarket cam that doesn't build manifold vacuum due to the valves being left open all the time, you will have less ability to apply the brakes than you do right now.

As I keep preaching: Power brakes doesn't stop the car any faster or in a shorter distance. Power brakes are of value only if you have an automatic transmission and live in a an area with a lot of stop lights. It keeps your leg from growing tired holding the brake pedal in while waiting for the light to change. As far as that goes drum brakes will stop a car just as fast as a disc brake will for the first time. It is only in road racing where you spend six hours of a twelve hour race with your foot on the brake and the other six with your foot on the gas that you need disc brakes. A disc brake can cool off faster, shedding the excess heat of road racing. If your not road racing a drum brake takes less effort to operate (easier on your leg) because they are self actuating. They are also lighter so your car rides better.
