I have an ERA 427 with their aluminum radiator, cast block (427CO) and aluminum heads. Running 180 degree t-stat 25%
antifreeze solution.
At driving speed even on hot summer days my engine temp runs aroung 160 to 165. When you stop forward motion engine temp will climb to 180 and the fans come on. In the spring and fall when ambient temps are in the 50's the car at driving speeds runs 155 to 160.
Any ideas on how to keep engine temps around 180 all the time. Does anyone else with a 427 ERA car experience this. I am sure the temp gague is correct and
oil temps almost mirror the engine temps (slightly cooler). I have tried 3 t-stats with no change.
