1971 Duster Handeling

I have the stage 2 qa 1 suspension and a Hotchkiss front sway bar, and a new borgenson steering box. Would be interested to know besides the chin spoiler whats done to the valiant? That spoiler dosent look that bad actually. So basically no bone stock mopar besides a gen 3 b body can do140 to 150?

They can do it. With right gearing and motor.

But driving it is not going to be a walk in the park like modern cars.

Still haven't answered some basic question on what YOUR current setup is that you have issue with.

  1. What tire size, brand, and model are you running?
  2. what is you front torsion bar size
  3. what rear spring do you have
  4. what shocks do you have
  5. what are your alignment specs
