Looks amazing Andy! I see you installed a distribution block with the 4 wheel disc brakes. My 4 wheel Wilwoods kinda suck, the front brakes are too small, and I think I need the smaller bore master cylinder but I've also had people tell me the distribution block can be removed with 4 wheel disc. I hate to remove it though because all the lines are nicely bent to it.
Whoever told you that probably didn't know the difference between a distribution block and a proportioning valve. A distribution block is just a block of brass with holes drilled in it. It doesn't do anything to brake pressure. It is just a couple of T fittings that are joined together so there is no reason to remove it or not use it. The question about using a prop valve with 4 wheel disc brakes is more complicated. In theory you don't need one but for home built brake systems it is probably a good idea to install one. Most people don't know how to design a brake system so having some adjustment built in is probably a good idea.
