beefy front end?

With the 440 in your A-body I would install the .89 torsion bars, unless the car will only be used for drag racing. A lot of people sell upgraded torsion bars so shop around. There is a lower control arm strengthening plate that would help as well. They`re sold by Mancini Racing and are a simple weld on (about $25.00). The tie rod sleeves could be replaced with a solid tube sleeve and jamb nuts. Year One carries them (about $55.00). A set of HD shocks would round out things and if you don`t have disc brakes, you should get some as mentioned earlier. HTH.
