For conversation purposes since a torsion bar is simply a coil spring that happens to be straight there is more stored energy in a thinner diameter with more twist (lower spring rate). Follow John's recommendations as to front spring and shock and then let the car tell you what it wants. I would guess he'll recommend something on the order of a stock 6 cyl bar.FYI if the front springs are way too low in spring rate the car may have a tendancy to wheelstand that the shock can't overcome. Don't overthink your initial setup..remember the KISS principle (Keep It Simple Stupid!!) LOL
