Need handling help..

I have a 1972 dart with 440/727..The car handles horribly..got to slow down more than should around corners because it feels like a boat..the body roll feels like its going to tip over..will make you tense up pretty good! I rebuilt the entire front end, new bushings, ball joints, tie rod ends, everything but still doesnt handle very well. The car does NOT have sway bars on the front or back..Dont know if that would help much or? The thing is, i do want it to hook up, which it doesnt do well, so not sure if adding a front sway bar will hurt it worse in that department..Advice would be greatly appreciated! I know its not going to handle like a corvette and i dont expect it to, but its kinda scary and i know it can be made to do better.
Thanks!
