DeWitts Radiator
For those looking to reduce coolant and oil temps, this is a good answer.
I have 450RWHP getting ready to do a 403.
Coolant temps run constant 195/200 with stock radiator. Oil temp with no cooler runs at 215/220, 290 at the track. This is with a 175 stat and fans reprogrammed.
Now with a DeWitt with oil cooler. Oil and coolant temp warms to 175 super fast. Coolant never left 190 mark. Here's the good part, oil temp is at 200 after a 65 mile test run. One high speed run temp peaked at 220.
