I have been have fighting the cooling issues with my '67 Dart for a while. I measured the width of the cooling tubes in my stock 2 row radiator and they are 9/16" wide. Is this a normal width? The radiator is the 22" '70 and later style for the aluminum pump.
 
Yup, that's about right.
 
Now I know why an aftermarket 2 row with 1" tubes is so much better.
 
Have it recored ... but ask if you can still get a MODINE ... MORE tubes and alot closer .... I did this to 2 of my cars and NO cooling issues !
 
Why not diagnose it before you throw money at it?
 
Been doing that for a while. This engine ran at 180* all day long no matter what the temp was when I had it in my truck, it had a 3 row radiator in it. Put it in my car with this tiny 22" 2 row and it heats up. It doesn't come to a boil or overflow. Just runs a lot warmer than I like. I dont like 210*-220* temps in hot weather.
