Any way to "de-power" a power steering box?

I find that tough to believe. One reason "the belt off" makes them so hard to steer is the gearbox sort of has to push the fluid around. If you drained the fluid, it would be easier. But there is GOING to be more play in the steering, because now you are moving the control valve.

Steering box in 71 swinger kept blowing up PSpumps and hoses. Have been driving it for several thousand miles without PS pump or fluid in gearbox. Not that hard to steer. Lots of play (box was shot to begin with I believe). Hard to stay in one lane (only on bad roads) only when I let off the gas LOL. Probably not safe? Been trying to find a manual gearbox and shaft forever. Car has v8 K member out of ?. with disk brakes LBP. Don't even know what I really need (for manual setup). I'm too cheap to buy flaming river or Firm feel box. Keep driving it cause it smokes the tires and runs consistent 15.00 at the track LOL. 2nd place street legal drags 2013 season. 2.5 hours each way to the track.
Can you drive it this way. Yes. Is it grinding or making noise? No. Is it safe? Will it fail? haven't found out the hard way yet!!!!
