engine build for reliability

So let's say you are going to build a small block and the most important goal is reliability. Say your daughter will be driving it. I have a 70 Duster and 69 Dart and both are pretty much blank slates. Both are 318s/ Here are a few of my thoughts.

mini-starter
Toyota alternator
MSD ignition and distributor
fuel injection? Not sure of type
bypass alternator gauge, continuous high-current wire thru bulkhead fitting.

What would you do? Say expense is no object.

Use which ever has the best 318. Replace the timing set up with a 340 double roller set up, including the drilled bolt for oiling. Replace the freeze plugs with brass ones, hoses and clean the radiator, fill with 50/50 mix of Prestone antifreeze. Change tranny fluid, filter, and adjust the bands. Replace seals and gaskets on engine, rear, and trans as needed. Check the rear bearings if 7 1/4 rear. Rebuild the carb, and replace the choke and choke pull off. Use a Chrysler electronic distributor, box, Taylor Spiro Pro helical solid wires, and platinum plugs. Run a headlight relay kit. OEM alternator is fine with an electronic voltage regulator. Good suspension, Brakes and Great tires. Clean it all up and Enjoy.
