so i added ssbc front disc brakes and a ssbc manual master cylinder,but brakes dont have much stopping pawer,i hve the correct pedal,but i am wondering should i remove the factory junction block and add a proportioning valve to the rear brakes and run no junction block to the front brakes?
the car was originally factory manual drum brakes all around.is the junction block restricting brake pressure to the front disc?

It's worse than that
The stock master cylinder would be set up for 4 wheel drum brakes with the same size ports and valves (roughly)
Just get a master cylinder for a Mach or Boss that has disc brakes (it will have a bigger reservoir for the front)
Then play with proportioning valves
Put a booster behind it while you're at it
Good luck
