Personal note;
Above table is based on roughly 30 year old information, which was considered on par with the times.
But, in my opinion, these days, normal “modern day” streethandling make torsion bar rates of 200+ pretty much the ‘default’ application for V8 powered A-B-E body Mopars.
Improved shock technology, needed with thicker torsion bars, upgrade the handling of a ’60s/’70s Mopar greatly.
