Front Suspension Upgrade Recommendations

I just acquired a 72 Challenger that came with a 318 but I'm building a 440 for it. The current front end is very soft so am looking at upgrading to the Bergman 1.14 torsion bars. The front end alignment seems like it needs more caster and I see the adjustment cam is maxed out so look like it will need more help there as well. Looking at the Bergman Gen1 UCA's.

Thoughts?
