antifreeze percentage?

[Rapid Robert]

63 dart 360 stock car. what should I use for coolant? racing will be in warm months from april to september. I may or may not drain the system when it gets cold depending on what you guys say if we go with no antifreeze. I had heard that distilled water is preferred & iirc? there was something about ionized water being better thank that but this might be my OCD acting up. and there was something about using a can of antirust/water pump lube when antifreeze ain't required. not using a thermostat. what say you guys and thank you for your time.

Check with your track. Some don't allow anti-freeze, it's a pain to clean up.

Iron cooling system or are there some aluminum components ?

Reverse Osmosis water and water pump lube and a wetting agent (water surfactant).

Cools better than anti-freeze.

Walmart close by sells 5 gallons bottles of water that been thru reverse osmosis among other purifications and ace hardware has water surfactant and I'm sure my parts house will have water pump lube. much appreciated! thanks guys.
