1970 Dart big block engine swap.

What do I need to know about spindle and disc brake upgrade kits? I want to keep the torsion bars.

Doctor Diff has all the basics covered. There are lots of options for disc brakes using mostly factory parts. I'm running 13 inch Baer rotors with Viper calipers on my Duster. I have the stock '73 type front suspension on the car with torsion bars.
