since replacing the radiator on my 29 tudor, I have driving the car daily and dont woprry much about where I am going. with the 30% Mitchell overdrive I can cruise comfortably between 50-60. wish I'd coughed up the $600.00 for the new radiator 15 years ago.
You know it's amazing what a new radiator will do for you. After battling my own demons for a couple of seasons I replaced mine with a unit from Bergs. Even on the hottest of Oklahoma days this summer it never got over 190 on my temp gauge.
