Power steering box question

Here is what I know from the past. In the 70's when I drove them like I stole them.. If you can 1 finger it easily they lock up when getting out of the throttle to save it in a slide. The later boxes that had a firmer feel were less susceptible to doing this. One reason that if I had a car with big HP numbers that you had to aim not steer. I would go to a manual box. I would be very happy if they made my power steering firmer on my car if I were you.
