Torsion bar question for 440 A body

I have .890s for my Barracuda which is what we have run in my son's 440/4sp Dart convertible. Both cars have factory big block sway bars, too. I really liked the .990s we had in my other son's Barracuda fastback, but I also liked the 1.14 bars we put in it later with BIG sway bars.
