power or manual brakes

Thanks for that redfastback, you answered one of my unasked questions(14"vac), I have a vacuum gauge, should hook it up and see what vac its running.Does a cam of this size effect vacuum at all rpm? 360 with 474lift/280dur. I take it the master my car has now is more for power brakes and has a bore larger than 1"? thanks again any help is appreciated.
