Right on the money.
Move the pivot for the push rod approx. 1 1/2" higher on the pedal . ....you may need to put on a adapter on the mount to locate the master cyl higher to keep the pushrod straight..
This will increase the pedal ratio to around 6-6 1/2 to 1 and allow higher pressure without higher effort.
Stock powerbrake pedals are only about 4-1 ratio........Adj prop valve is for biasing initial pressure front to rear and has little effect on holding on the line.
