If I converted my mustang's old drum brake to new disc brakes using the scarebird kit, do i have to change the mastercylinder too, or can i just keep using it

The front brake portion of the master cylinder is entirely different for drum brakes verses disc brakes, as is the proportional/differential valve.
Also, if they aren't power assisted, the braking effort will actually increase with disk brakes because they aren't self-actuating like drum brakes. The big plus with disk brakes is their resistance to fading due to heat build up in drum brakes.

if you want them power disk brakes you do and if you do get power you have to have a proportioning valve so your rear drums dont lock up
