Got an 83 Ram Charger with a 440 today!

The Ram Charger has a large radiator but it appears to have a small leak and is pretty coroaded up inside. There are at least three other RC's at the local 'Wrench-A-Part' that all appear to have good radiators but all have 318's in them. They should bolt right into my RC since it originally had a 318, but would it cool the motor sufficiently?
