Improving handling, steering, ride. 72 K5 CST (Pics)

[Dclassen]

Basically I just replaced the Engine,exhaust system, radiator, ac compressor, rebuilt transmission and transfer case on my truck. I'm still not really happy with the way it drives and handles basically. It's terrible offroad(has 3" body lift). What can I do to improve the ride and steering? Oh and on this desert trip it bounced around so much the engine went out down a hill along with my brakes, almost had a heart attack. I just want this thing to drive nice-ish Pics ofc.

Edit: Just added link to image album the pics were huge.
