how much trouble to....

Thanks everyone for all the replies and so quickly!!! allegedly, the whole front end and box is new, but when I drove it, the steering is just loose and vague. you turn a corner and unless you physically turn it back, it stays in the turn. the box may need to be adjusted some. I've done that on gm's before with good results. I had built a 67 cutlass for my son and did an LS swap in it with a 4l60e tranny. had to change the box in it, even with power steering to a quick ratio and after adjusting it, was much better. 400 in this car is more or less slightly modded, no headers.
