Is there a different master cylinder for improved braking?

[Eric F]

70 Road Runner 11 inch manual drums at all 4 wheels. I just did rear brakes with drums, shoes , wheel cylinders, springs kit.then I’m doing the fronts next using muscle car front brake shoes.I’m wondering if there is a difference master option without going power brakes. Thanks
