Evans Coolant Temps

For decades the folks in the racing world have used just distilled water and a bottle of water pump lube. Ran it in a Trans am car for 3 years never had any issues.
Very cheap and the best heat transfer you can get.
True but I also don’t want to have to deal with what I’ll have to go through to get the 340 in my dads old bracket race car up and running. Took the rad cab off and just solid chalky calcium build up. Put the cap back on and went back to working on my dart lol.
