14" fan + 360 = overheat

OK, so it would appear that I have the oddball (and more expensive) 22x25 3/8 radiator, rather than the more common 18x22. So of course, it is more expensive to get one from US Radiator.

Are these radiators interchangeable? I can't imagine that Dodge had two different core supports just for a radiator. Does the 18x22 have a wider mounting flange?

US Rad says my B&M cooler should be enough for the transmission, if I want to go with the Tripleflow. But, I think just a 3 core with a good fan setup like Goody's will do the trick.

I'm going to call around and find out the cost to recore my unit before I get my heart set on a US Rad system.
