68 Dart GT suspension upgrade recommendations - best bang for the buck

I meant 225 (slant 6). That was the original motor. Now has a 360. no sway bars either front or rear. Car has 15" tires front and rear. I have no idea what if any upgrades were made when the bigger motor was installed. Torsion bars measure .86" I was told the ball joints are new.

If it we're me with this car to start it would be in order

1. Welded in Subframe connectors
2. Offset Moog upper A bushing install for castor/camber
3. Good tires with modern tread design, traction and temp ranges.
4. Alignment for modern tires.
5. Good shocks noted above
6. Front and rear sway bars or at least stock front.

Drive and enjoy until your ready to step up to more if you want to.
