My 68 Dart I have a 505 , Edelbrock RPM heads, hi flow 440 Source water pump , 180 degree thermostat 26" BeCool radiator 2 row , flex fan and shroud , 90s degree temps outside it will get as high as 190 195 sitting in traffic start moving back down to 180 , 185 . Had the same set up in my 71 GTX with a 515 Except it was a Champion radiator ,same temps. With a steel fan it would cool even better. I am not a fan of electric fans unless there is not room for a manual fan and shrouds on either are a must. 50/50 is all i will run all the other crap out there i have tried with poor results for the money spent.
