should work
I think it might work, if you use an adjustable proportioning valve and the right residual pressure valves ( 10 psi in front & 2 psi in rear ). Put the proportioning valve in the front line w/ the 10 psi valve, adjust propostioning valve so that disc start to brake before the drums. This works in street rods, but just in reverse. You can get it all from the Speedway website. There is a diagram in their catalog that might help, just do it backwards for your Olds.
Good Luck!!
