Vague Steering, How to improve?

Currently I have a stock manual steering box in my 1973 scamp with a big block motor. It is 2.5 turns to lock each way so I assume that is 24:1. I do not mind the ratio but I can turn the steering wheel 45 degrees without much turn of the car at speed. Very vague feeling. The entire front end is new with a kit from Dr Diff with
2 NEW powder-coated upper control arms with bushings and ball joints INSTALLED
2 Lower ball joints
2 Outer tie rod ends
2 Inner tie rod ends
2 Tie-rod adjusting sleeves with clamps
2 Lower control arm bushings
2 pairs, strut rod bushings (2-piece improved design).

Is this normal to have so much vagueness in the steering? What are the options to reduce the vagueness. I am not going to do autocross. Most of the time on the street and some drag strip stuff. I have the camber at -.25 both sides, caster +2.5 and 3.0 with essentially 0 toe-in. Is this a sign that the steering box is worn and needs to be rebuilt/replaced? What can I do to reduce the sloppiness of the steering wheel?
