Clanking on drivers side over speed bump

If you want better handling, consider 1.00" or 1.03" torsion bars, stiffer rear leafs (like in the 150 lb/in range), and front and rear sway bars. About 1"-1 1/4" diameter for the front and 3/4" for the rear...


That may wake it up a bit. We're doing that on a 71 Valiant 4 door with a 360....

Torsion bars are right on, but the rear springs shouldn't be that stiff, especially if you're going to use a rear bar. The front end was undersprung from the factory, but the rear was not. I have 121 lb/in springs on my Duster. Duster's a 108" wheelbase vs the barracuda at 106", but it should be fairly close. Most of the "handling" leaf springs are ~130 lb/in (Hotchkis, Bergman's custom Eaton's, etc). Even autoXcuda, who runs the Hotchkis springs, unhooks his rear sway bar on tight courses.
