Torsion bars for stock suspension rebuild

JLP - Define "very firm":bounce:

I'm planning a complete suspension overhaul on my 75 Dart Sport, and I want to give it much improved handling for the street, without turning it into a haywagon ride. It's originally a 318 car (no sway) and I am looking at doing a total rebuild with either .92 or .89 bars. I'm thinking the .89 set should hold up the front end very well with just a smallblock in it. Any thoughts?

Also what brand of sway bar do you have? I'm looking at Hellwig and Addco. I like the Firm Feels, but they are more of a race bar, and this is a street car (read:waste of money).
