What suspension upgrades should i do for $1200 big block dart

I am trying to lighten the front ,aluminum heads,aluminum,water pump housing,mini starter,headers,Battery to the trunk,aluminum radiator and possibly the borgeson power steering box

Heck if you did all that the car would probably be lighter up front than a stock small block car.

You've already got a good start with the 1.03's. If you're running the stock leaf springs out back it would be good to upgrade those. It's not as dramatic a difference as adding the larger torsion bars up front, but it makes a difference. I'd go at least to XHD's, they're about 110 lb/in. But anything from 110 up to 130 lb/in would work well. I like the mopar oval tracks, but they do set the axle back a little further too if you run them with stock hangers (it's only a 1/2" at most). Other than that I'd go with a set of Bilstein RCD's and some sway bars front and rear. Tubular control arms are nice, but all you really need for a street car is the Moog 7103 offset bushings and your alignment set around -.5* camber, +3* to as much as you can get for caster and 1/16" toe in. You can get more negative camber and more positive caster with the tubular arms, but it would be overkill with the BFG T/A's. They'll be the limiting factor if you add the shocks and sway bars.
