Which "drag race" master cylinder?

a 1/16" inch increase in master cylinder bore size requires a 12% increase in leg for the same pressure
a small 15/16" master and a 'cuda 2 3/4" caliper piston will stop effortlessly,almost like power brakes.
..if you go from 15/16 master to 1 1/16 you will require 24% more leg

Exactly backwards
smaller master increases pressure but increases pedal travel .
15/16 bore master and 2 3/4 piston (cuda caliper ) on an a body will stop effortlessly
1 1/8 bore master and 2 5/8 piston (a body caliper) will make stopping very difficult

a 1" master with 100lb of leg will produce about 3600 psi with the a body 2 5/8 caliper
a 1' master with 100lb of leg will produce about 4400 psi with the e body 2 3/4 caliper
a 15/16 master will increase the pressure even more but there will be a bit more pedal
travel.
use the small master and larger disc caliper and you will have great brakes.
