You could do it but I don't think you will be very happy.

Drum brakes are what is called 'self-energizing'. Once you apply the brakes the design of them helps you apply the brakes. You might have noticed that the e-brake holds better going forward then reverse then backwards...same reason.

When you go to disc brakes they are not self-energizing and will require more effort to stop the car. Maybe you could try pluging the vacuum line to the brake booster on something with disc brakes that is about as heavy as your car to see what it feels like.

If you deside to do it try and find as small of a master cylinder and as large of calipers and rotors as you can find. You might want to look at aftermarket calipers too.

I think using a step-bore MC like the 82-up GM aluminum ones would be a good start. They use the larger bore only till the pads hit the rotor and then transfer to the smaller bore. It will help keep you from having a too much peddle travel. S10's used 15/16" bore MC's...I don't know if you can get smaller then that.

do you have the parts and stuff???

if your tryin to do it easy on the wallet...try scouring the junk yards for another abody 64-72 chevelle, gto, lemans, gs, skylark, 442, cutlass, monte carlo, gran prix, 68-74 nova. and take everything, spindles, backing plates, lines, master, linkage. You might be able to do it cheaper than a kit....i havent done it yet so i dont know, you might be better off with a disc conv kit everythings new and you dont have to fool with finding parts.
Good luck to ya.
