Best torsion bar for a Hemi

I have daily driven my '73 Dart with 1" torsion bars and a 318/360 under the hood. Currently have 1.08" bars.
FORGET the "autocross / roadracing" term. It comes from 'outdated' Mopar-literature.

IMO, 0.9" to 1" bars should have been stock from the factory in any A-body with a V8.
