Best torsion bar for a Hemi

Okay, Gents. I would like your thoughts on the best torsion bar for a Hemi A-body (Dart).

I believe the racers used the lightest possible (slant 6) but I would like to drive this thing on the street.

I have a 1” firm feel but I think that’s too stiff. My car isn’t for auto cross.

I’m leaning toward .890 which I believe is the police chaser diameter. Or, .810 would probably work well also.

Going thinner would also have the added benefit of header clearance.

Curious what you all run (mine is not a drag car so much as a street/strip car). Thanks in advance.
