Torsion bar size??? 74 Swinger

yeah the idea is to install the torsion bars while I'm at redoing the front suspension. Ill have the /6 in there for a few months but hopefully over next winter I will have a 360 to put in it. I want a decent ride. will the 1.03 bars do well with a 360? I would like to find a happy medium ya know? for ride and the occasional run down the track? I will also look at installing some sway bars. The body rolls terribly lol
