I used a stock front disc, rear drum manual master cylinder w/1.25" bore. Installed the clevis pin in the highest hole in the brake pedal assembly. Set the adjustable proportioning valve to feed 55% pressure to the front discs. Car will now stop from 125 MPH fast and easy enough to make the first return road with ease!

Yessss!
Big block? Small Block? Nope, It's a Pontiac Engine!
