Six cylinder torsion bars with big block

I hear Ya Rani. I just did a /6 - 400. For the time being for now, I'll have to run the /6 bars and the 9 inch drums up front. 11 in here in the rear. But! LOL, I'll not be driving far or hard with the car like that.
For me it is more of a brake upgrade issue. The T bars can stay since this Duster is more of a drag effort.
For the street every day driver, in my heart I can't advise it.
