Has anyone put a delphi 600 power steering gear box on their car ,and if so did you add the more positive caster then. What i am asking is if you did are you satisfied the way it drive's. I have set caster as much as possible with existing upper a arm's and honestly if the a arm swap to increase more caster does not improve road feel , i think i might go back to a manual gear box. I once installed a stock power steering on a 65 chevelle school car, for easier parking. I know how it drove on the high way before , and after did not have the road feel. I remember my first new 63 did not turn that hard anyway with manual steering, and drove fine, even though it had bias ply tire's It just is very sensitive, seem's like you go over a bump and you tend to over steer.??????? Yes , toe is set and camber.
