Torsion bars the bigger the better???

Seems the trend is to get >1.00 at a minimum nowadays.....with a good shock. Not sure why Mopar didn't do this from the start with the B/RB A's if it was such an improvement.... I mean they had million dollar suspension dynos and could probably replicate any torsion bar rate but they stayed with the .8xx for even the big blocks?

It's because the tire technology sucked 50 years ago. Too stiff and it overpowers the tire sidewall tech that was available to them from way back when. Nowadays modern tire technology and wider tires can keep up with heavier torsion bars or a heavier sway bar. Also the designers had to strike a balance between too harsh a ride and too compliant. Most people bought this stuff for daily A to B transportation and needed to live with it every day. Radials didnt really hit the scene until mid 1970s. Until then it was bias ply or fiberglass belted tires.
