Can I use the same master cylinder I have with a power booster by itself for a manual brake setup??
I'm building a 72 chevelle with a BBC. It will not produce enough vacuum to support a booster and i need the room for valve cover clearence. Can I use the same MC without the booster for a manul brake set up??

From my recent front disc conversion on my 66, yes you can. I ordered the Ground Up front disc conversion kit, less the booster, because I did not want power.

It fit and works fine.
