As I said I'm ignorant to the models and applications. It is in fact an all Al core, as I've indicated, it's core is 30"x18"x2". I just know it is big and from a ford, which i believed to be a powerstroke...

Does that change it's desirability? I'd like to sell it but I'd feel better if I knew what I was selling.

 

No worries, mate. Some guys swap the 6.0 liter cooler into 7.3 trucks because it's a tad bigger, but has plastic/polymer ends so it is easy to distinguish from the all alloy version from the 99-03 7.3 trucks. 'Strokers before 99 weren't factory charge air cooled so it is a pretty simple puzzle.

Powerstroke intercoolers are pretty popular with the Turbo Buick crowd....

 

99 and 2000 had the AL tanks, from that point on it was hit or miss if you had AL or plastic tanks... My 2001 had plastic (and still does but its 6.0 plastic...) but my wifes 2001 excursion has AL...

That being said, once the end tanks were modded to 2.5" intake and outlet its all but worthless to the 7.3 crowd...
