overheating 427
I have a 427 bbc with an over heating problem. should i replace the 50/50 coolant with only distilled water ? if not what should i do ? i have 160 degrees thermostat and i cant seem to lower the temperature of the water. i fixed the timing, i have aluminium radiator with 3 electrical fans.

When do u overheat? driving on highway or city? Do you bleed the system? Do you have air dam? All 3 fans working correct?

Re: overheating 427
i think its a combination of timing and the 160 stat your using. The stat is too cold and opening too soon and not letting it cool. sometimes the cold stats doesnt mean a cooler engine

Antifreeze and water will cool an engine better than straight water...Also you could try water wetter. I found it dropped my temps in my 360 Dart Swinger by nearly 20*.

Coolant just lubes the system seals and keeps things from freezing in winter.
You can use strait distilled water and water wetter with great results but only in summer.

Re: overheating 427
Need to know much more about engine to know what it will take to fix your problem. BBC was a tight fit I'm sure. Lot of things to consider with the rat stuffed in there. Heat soak from tight quarters has a big effect on everything, stuff you wouldn't even think of.
