Six cylinder torsion bars with big block

I've been swapping 6 cyl. bars INTO all sorts of Mopars since the 70's, and would never consider any other way. Here's why.
The 6 cylinder bar has to be twisted tighter to maintain the weight of a Big Block or Hemi at normal ride height. When you hit the gas, that extra stored energy in the bar will spring the front end higher the instant torque is applied to the rear axle. The difference in traction is night and day. A lot of cars with thicker bars will bite at the hit, and then break traction right after the snubber finishes its upward movement. Getting the nose up quicker will make a seamless transition between the hit and full weight transfer.
Bottom line is that any big block A body is a handling travesty...if you want something glued to the curves build an aluminum headed SB, or even a Slant (I don't care how much horsepower you've got...a well tuned Slant will eat you alive in the curves. A BB A Body is a DRAG RACING package. Treat it as such.
