Quote: I suggest you look into what the factory combination valve does before you dismiss having one or think just putting an aftermarket adjustable proportioning valve in is the same.
The '70 GTX drum/drum unit is just a distribution block.
A disc brake car has a prop valve that regulates how much pressure the rear sees. For this application the current block is just fine, the problem is I'm not getting enough force on the FRONTS, not too much on the rears.
I need to find out why the fronts are acting as they are, the current block being used will have no impact on the issue.
