engine build for reliability

I agree with a previous post. These cars are very reliable the way they are if they are maintained well- quality parts, good mechanical ability. The only thing that might improve it are some modern upgrades. They would be electronic ignition (Mopar) and a simple bolt-on fuel injection. The rest is just good maintenance- good rubber parts, hoses, belts, tires. Change all the fluids- engine, trans, P/S, brake, rear end. Good quality brakes. A new battery. I did these things for my kids.
