does not suprise me at all that a 440 running a 22" radiator is having issues.




Some 440's do have heating issues others don't.

I was 2nd owner of a 69 Chrysler 300 four door with a factory 440 HP engine, it had a 22 inch, 2 row radiator with a shroud, no air cond., it would go all day long in any kind of driving and never run hot.

The original owner ordered the car with the HP 440 engine so he could tow a good sized camp type trailer, which he did every summer.
