That's why I suggested you start with a pretty simple baseline of s-bars, see if it provides the results you want, then maybe down the line step up to the control arms. Then you can get a feel for the incremental improvements
Interstingly enough, I actually toyed around with the relocated upper control arms about ten years ago on a pavement street stock. The improvement was pretty decent, until tech got wind of it and made me change them back to stock. I used a short, I think it wqs inthe range of 7", offset ball joint, chevy style that mounted in a pad that hung off the side of the frame rail. Camber and caster were never a problem as I could get huge amounts of either. The shorter upper arm also created a greater camber gain curve as well over the stock units, although it wasn't needed as badly because of reduced body roll that came with mondo t bars and s bars. I seem to recall the net cost was around $60-75 and half a day on a mill.
Another item we toyed around with were chrome moly, tubular strut rods with a chevy ball joint on one end. These would bolt to the K frame with the ball joint with a fabricated tapered end on the control arm. This eliminated a lot of the braking compression a bushing sees in that application and now you see similar designs marketed for big dollars. Another low buck deal that I think was under $50 total. Heck, I was just trying to go faster and never thought any of these things had a market for them. Really, ten to fifteen years ago, you could rarely find a mopar guy who wanted handling unless it would reduce their e.t. at the strip.
