    I have owned my car for 30+ years and had manual brakes since I bought it. They work great and never gave the pedal pressure a second thought. I switched to Wilwood brakes years ago and used a 7/8" MC (IIRC from a '68 Corvette). Works great but needs a proportioning valve because the rears would lock up first under hard braking since the pad surface area on the rears is large. Just make sure you use the top hole in the pedal and a smallish (7/8" or 15/16") MC or you will have to press real hard to stop.
    Recently, I bought a 7/8" MC from Wilwood and it required me to modify the pushrod length. We will see how it is once the car is back on the road.

    The reason for no power brakes is because on a race car there is no vacuum to supply the booster. I run a 600hp SBC 383 with a 108c/l cam I use a electric vacuum pump to supply my booster and I love power brakes

    biker , not a port on the spacer if you have a 1' spacer they have a90* elbow that you put on the manifold the 1' spacer gives enough room for carb to clear the manifold port

    Keep the vacuum assist set up, you need longer stopping distance with manual brakes. New cars stop faster and the way I see kids cutting in and out then jumping on brakes is scary. Manual brakes were not made to handle quick stops in short distance, the vaccume assist is better although they pale in comparison to newer systems.

    Oh, I assure you it's not just kids, you should see how both my parents drive, it's terrifying.
