Suspension/Chassis Suggestions - 70 Dart Swinger

I have read through quite a few suspension threads and find myself more confused/undecided than when I started. I am looking for suggestions on how to proceed in regard to the suspension and chassis setup, the end goal is to have a sporty daily driver. Initially, just to get it running/driving I am installing an 80s truck 318 but I have a 2/3 complete 451 stroker with aluminum heads I might install later. I have some time to save up as I am still putting it back together but priority is getting this car running and driving and upgrading over time, I just need a solid plan on how to meet my goal, below is what I have:

Car info:
70 Dodge Dart Swinger 2 dr Hardtop
225 CI 6cyl - removed and sold
3 spd auto on column - removed, converting to 4 spd
7 1/4 rear axle
4 wheel drums


Suspension/Chassis Parts I have:
Refurbished factory 73+ UCAs, LCAs, strut rods, V8 K frame and disc brake spindles with Energy suspension's Poly Master kit
Stock replacement ball joints
Wilwood Dynalite Pro front disc brakes, 10.75" diameter vented rotors - 4.5" bolt pattern
6 cyl Torsion bars - still in the car
6 cyl Leaf springs - still in the car
8 3/4 housing w/ 489 sure grip center
axle shafts - 4.5" bolt pattern
10 or 11in drums, I believe I have both
Factory power steering gear box
Stock tie rod ends, adjusters, pitman arm and idler arm
Comp Engineering 3 way adjustable drag shocks - probably won't use these.


These are the parts that I believe that I need to purchase to increase the performance of the suspension to meet my goal, what would the priority be in order of greatest benefit first?

Torsion bars
Rear leaf springs
Shocks
Sway bars(front & rear)
Chassis stiffening
UCA upgrade
LCA upgrade
Ajustable/dynamic Strut rods
Delrin bushings
Wheels
Tires

The 6cyl suspension is still in the car because I have been working on the body and rebuilding the HVAC. The rebuilt stuff is not in the car yet so now is the time to weld in the reinforcements to the LCAs and K Frame I assume. I also assume that torsion bars, leaf springs and shocks should be installed at the same time as the front and rear axle assys, please correct me if I'm wrong.

Thanks for the help!!
