So I finally decided to clean up my brake line setup as I got tired of how hodge-podge it looked even though it worked just fine. I have manual disc/drum setup. I ditched the factory block and manual proportioning valve and picked up a new distribution block w/proportion valve assembly from NPD. Pretty much a bolt in with some minor line bending needed as this was originally designed for Power Disc/Drum setup, not manual disc/drum which is what I'm running. So I got everything replumbed and hooked up, start the bleeding process and when I get to drivers side caliper to start bleeding, I have 0 fluid coming out. Thought it might be the caliper so i disconnected the brake line and had my daughter push the pedal, nothing, no fluid coming out. Thinking maybe the brake line was plugged up I disconnected it from the distribution block and depressed the pedal again, nothing, no fluid at all coming out of the port in the block for the left front brakes. All my others were fine. Any ideas? Could I have a bad distribution block?

blow compressed air through the line first to be 100% sure its not the line(yes, it puts air in the line...but since you have to bleed it anyway...

That sounds like a block issue to me. You can disassemble it to check the gaskets are installed correctly. Let me know if you get any leaks at the brake switch port. Every block I have tried has leaked from that port (which should be dry) I am now thinking of going to an adjustable prop valve.

You have got this far... so finish properly...
CLean ALL you lines...
blow all old fluid out with compressed air...
clean the lines with warm/hot soapy water... used compressed air to blow through LOTS.
blow air through to empty the water.
force methylated sprits through the lines to remove the water.
blow DRY air through the lines to dry out the meths.
Fill your lines with new brake fluid.
Bleed, adjust and enjoy!!
