Hey folks, the 413 in my 72 has been running at about 215+ rollin down the highway. Replaced the thermostat, replaced the clutch fan, added "water wetter", etc.. etc... It has the original radiator in it and Im fairly certain its stopped up.

So, the question... Have a custom (yes it will probably have to be custom) aluminum radiator made or take the old one to a shop to be rodded out? I think "long term" the aluminum is the way to go.

Vehicle is my 1972 Rectrans Discoverer 25 motor home on a Dodge M350 Chassis with the stock 413 and Loadflite trans.

Laine.
