Torsion bar question 6 vs V8??

Some people bought into the idea that bigger bars make the car ride too stiff.
The Direct Connection and Mopar Performance books and literature pushed some good info but some bullshit as well.
Remember the "thin wall 440" myth?
The factory used very conservative torsion bar sizes to coincide with what consumers wanted at the time. Soft ride, small tires, over boosted power steering....all the sort of thing the buyers seemed to want back then.
I have 1.0 bars in a 67 Dart with a 360. It does not ride harsh.
I have 1.15 bars in my Charger. That car rides great too.
Going from .85 to .89 bars is pointless to me unless the .89 bars are free.
