Help needed! Best cooking radiator for 67 Dart

Exjouster said

Hey all! Need help with what is the best direct fit cooling radiator to put in my 67 Dart GT convertible. Just put in a 69 340 mild build engine, but the old radiator can’t hack it anymore. Car is in Florida, so no worries about running too cold.

Do some searching and find a 2 row/core rad with 1.25" cooling tubes, to fit your ride. These are superior to 3 or 4 row rads. They offer more surface area with the larger tubes, so more fluid is exposed to cooling. You should hold steady at 175-200, depending on highway or city driving.
