fall river, ma
i was wondering if anyone knows how many rows a stock 4 cylinder radiator is? 1 or 2 ? i just finished converting a notch 4cyl to 5.0 and all i had was the 4 cylinder radiator, and my engine runs pretty hot. not overheating, but hot. i think the v8 radiator is factory 2 or 3 row?
 
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).

No, i bought my notch as a shell with no engine or transmission. The previous owner was already using the car with a 302 and t5, and made all the other changes, like rear end for example. I just had the car towed to my house, and installed my engine and tranny. I'm gonna look into getting a 3 core radiator from autozone for $159. Can't beat that. The radiator i got is extremely corroded inside. I'm sure a mix of that, and being a 4 cylinder radiator, is the problem. :)
 
I checked my a Mitchell collision parts manual and they confirm that the 4 cylinder and v8 radiators are the same. If it is severly corroded, that would be your problem. You'd be much happier with the 3 row radiator. It will allow you to modify your engine and run it harder without the threat of overheating. It will also lessen drag on the water pump as it will be able to circulate the water much easier, especially at higher rpm.

They aren't exactly the same. The 4 cylinder radiator has a much smaller upper outlet. I couldn't use the factory upper radiator hose. I had to fabricate an adapter. But either way the rad i got is no good. I got a 160* thermostat, flex a lite fan (no clutch) and new coolant and no matter what i do to make the engine run cool, it still creeps to 210* which is just not right.
 
Yea, that's too warm. Definitely time for a new radiator! Especially if you plan on doing mods on the engine.

Engine already has mods.lol...planning on getting aluminum heads next
