FWIW, my drag car has the MC plumbed opposite of what I did with my street car. The street car has 4 wheel discs. On factory setups, the pedal feel is set by adjusting the REAR brakes. Not so in a drag car. Front runners don't stop nearly as well as slicks. Why would you put the brake bias to the front on a DRAG ONLY car? My street car , rear calipers have a bracket for the e-brake and when I first put them on, I didn't have the cable setup. Pedal feel was night and day after I installed the e-brake cable setup. Don't know about the OP's brakes. I would imagine his calipers are divorced from the e-brake.
