SSBC Conversion help

Do I still need the master cylinder if the bowl has two different chambers? I guessing front and rear. I was almost positive I was going to need a proportioning valve. I'm going to keep drums on the rear but I'll have to buy new ones or a rebuild kit. The car hasn't ran in 15 years is what the previous owner said. I have the motor trans and drive shaft out of it and I'm trying to build a street/strip car with the 318/904/ 7.25 although I haven't even gotten to any of that. I'm starting from the bottom and building up.
