Rad Swap??

Thanks for your comments and help...I've been informed that the only differance is the core size in the width department..(two) inches..20 vice 22. Now I'm wondering how much of a differance (in temp) this effect could be with the 2 inch loss which is = to a 6" square. Wouldn't that be like a dead bird stuck to the corner of the rad?? :lol: :lol:

Hummmmmmmmmmmmmm
