I'm looking at swapping in a 6.9 or 7.3idi into my 73 International pickup. The radiator from one of these first gen Dodges would be a good fit in my truck. I know I'm looking at more displacement but not as much horsepower as your alls trucks have. So I was wondering if these Dodges have any cooling problems when they're getting worked. Any first hand information is greatly appreciated.

Two minor malfunctions on 1st gen and I think that they go to all 12v - head gasket leak at the thermostat housing and fluctuating temp with aftermarket thermostats.

The appearance is that the design specs are 120 F ambiant and over 200 HP continous output. One of the ways to compare is to use square inches of core + thickness of core + fin count which will give an good guess on square inches of fin exposed to air flow. The radiator from a 460 Ford weights more but I did not measure it.
