During the era of Muscle Cars, Chevy brake pedals came from the factory with an upper and a lower master-cylinder pushrod hole. The top hole was used for manual brakes and the bottom hole was used for power brakes. Remember that power brakes require less ratio than manual brakes.
Another problem to consider is that some smaller boosters may not allow enough stroke with big production brake systems. If you do not have the room for a larger booster a smaller-bore master cylinder could be used to fix the problem. (I don’t even want to think about the troubles you would have to overcome to make that work?)
Another alternative is to use teflon-core stainless hose. This hose is the best to use for more powerful braking systems because they will not expand as easily under high braking pressure or heat. That expansion of the line will degrade the amount of braking power available and usually at the worst time.
