Comparing OEM radiators, it would be a 2 row in either the 4 cylinder or the 5.0L. If the engine is running hot, the radiator may have sediment in it or not be an origonal and not enough for the cooling demands of the 302. I would look in to a Ford Racing aluminum radiator or go to a local parts store and get a good 2 or 3 row radiator. With metal prices rocketing skyward these days, the aluminum radiator would probably be the most economical choice. Oh, and sort of off-topic, but do you still have the 2.3L drivetrain and all? Is it a manual transmission drivetrain? I'm in the market for a manual transmission (plus clutch, linkage, pedals, and whatever else goes with it).
