Best coolant for our 60-70's Mopars?

I see Evans coolant as a solution to a question that I never asked. Others have asked, fine for them. Not for me. Most of the time I can run straight distilled water without a problem. Straight water meets ALL of the needs and demands on the system except one, corrosion inhibition. Which is why I use green coolant in a 50/50 mix.

The singular only advantage for me that I see in Evans is that I wouldn't have used coolant to periodically figure out the legal way to dispose of in Kalifornikstan.
