New brakes, soft pedal, distribution blocks ?

So I have all new stopping components in my car, which is not road worthy yet, and have about 4-5" of travel in the pedal before it starts to firm up. Brakes are bled, no air, no leaks. Bled using a pressure bleeder, not vacuum.

Here's what I have:
68 barracuda manual drum brake car.
Frt Drdiff brembos
Rear Drdiff cobras
Braided flex lines
Drdiff 15/16 master
Drdiff adapter 4 to 2 hole
Stock manual rod
Distribution block from 69 valiant, not sure on brake configuration of said valiant.

Now I do have the distribution block that came off my car. There are a couple of frozen lines. That's why I used the valiant block.
Is there any difference between the two? 68 to 69 regardless of brake configuration? They look a bit different. Is there any way it can be causing my weird pedal?

Those are switches so if you loose pressure in the front or rear it turns the brake light on, the proportioning valve is another part and I don't think a 4 wheel drum system had them. you should use a adjustable proportioning valve so the rears don't lock up on hard stops.
