This is the reply I received from John Dingman at Dewitt: Our radiators are all made in Michigan. We have a full CAB braze oven and braze our own aluminum cores in-house. Our radiator comes with a lifetime warranty. We use multiple specialty alloys for the core, and most of the tanks and parts are 3003 alloys.

Here's another suggestion. Go to Entropy Radiators (Entropy Radiator | When Only Bad Ass Will Do). I got a two row aluminum radiator with two electric fans. Works great with my 525 HP, LS3. The build quality is great and the fans have aluminum shrouds, not plastic. It's worth a look. And its American made! Have fun with your project! Here's a photo from three years ago, when it was installed:
