It depends on what you use the car for. Is this a modified car or is it a stockish restoration? Is the radiator that you have the original one? If the stock look is important to you, you can always have the original radiator re-cored. They will reuse your upper and lower tanks as well as the original side brackets. You'll basically have a brand new radiator with a stock look. I think you can also have a thicker core installed as well.
