If you can't lock up the tires with the current manual brakes, adding a power booster won't help that one bit.
All a power booster does is reduce the amount of leg effort needed to push the pedal down, it does not magically decrease stopping distance. It was developed as a convenience feature, to attract female buyers and the older generations....grandmas and soccer moms.

if you've got the larger 1-1/8" or 1-1/6"" bore master meant for use with a brake booster, pedal will be harder and actual pressure at the calipers and wheel cylinders will be lower than if it had the correct 15/16" or even 7/8" bore master cylinder.
Knob on adjustable prop valve is just like a bolt.....clockwise is tighter, reduces pressure to the rear...counterclockwise is looser, opens the line to the rear more.
How can I find out what bore my MC is???? Thanks, George in NC

Pull it off the firewall and measure the lip of the bore at the back of the master with calipers or a good machinist ruler. You can leave all the lines hooked up when you do this, they have enough flex in them.

I used a CPP when I put Mustang II with disc on front and drum 9" ford on rear. Replumbed all of it. The CPP has a built in proportioning valve and was easy to adjust. No power brakes, stops solid

A quick measurement on my 63 Nova only has a 5.7 to 5.75 pedal ratio. My Wilwood 12" four wheel brakes are firm and do not lock up with a 1 1/32" Master Cylinder. Have been thinking of going to 15/16" after reading this article. It goes along with a lot of the above posts.

Math is Hard I went out and remeasured my peddle it is more like 6.5 to 1
To which my brakes should work better than they do.
