Advice on budget a/body bracket car suspension?

Hi,i am wondering what to use in the setup of my a/body.The dart is for strip only. I am on a budget like most and will need to start with mono leafs and caltracs,adjustable shocks and 295/65/15 et's or slicks.Car already has a little tub work and relocated springs,welded in chassis connectors and 8 point cage with kirky seats.What should i be doing up front to help with hook up,are the really light .810 torsion bars the way to go or can i use something a little bigger.Has rack/pinion steeing and thought 90/10 shocks,tube top control arms and factory bushes ect would do.car is to run fenderwell headers.Engine 440 world block based stroker.I have a set of .870 bars that are well used small block or will they be to stiff,trying to keep it simple but want to spend the money i have on the right parts the first time.Want to lift the tyres a little but be stable at speed.Plenty of u guys must have this down pat and i would be thankfull for your advice thanks.John.........
