Which "drag race" master cylinder?

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.
