Ok here is an update:
Finally found the time to plumb in a wilwood metering block with built in proportioning valve. In doing so many of the old brake line fittings were shot so I ended up making all new 3/16 steel brake lines front and rear and located the proportioning valve near the MC.
Flushed clean DOT3 brake fluid through the lines and bled the brakes, get a very firm pedal.
Took the car out with the rear proportion dialed all the back ( least possible rear brake assistance) and car has very little stopping power up front. Dialed up proportion valve and still very weak stopping power ( worse then when I had drums).
So the only thing not replaced and that is unknown is the brake booster and master cylinder.
1) could it be the MC has the rubber grommet used for drums and it need to be removed?
2) could be wrong MC all together?
3) should I replace the booster? It seems to be working fine.
4) any other possible reasons the brakes would not be working other than MC?
