4th gen radiator are unobtainium.
 

Seriously, they're out of stock everywhere unless you're looking for a fancy welded aluminum one. It's nuts. It took me like two weeks to find the one I just put in my car.

Found some on amazon but your right hard to find. https://www.amazon.com/gp/product/B0...J5EFZAEH&psc=1

You're right. rock auto only has 2 in stock for LT1 cars (bigger rad for LS cars so an upgrade)

I have a couple used ls radiators:)

I tried that, at first. The 'new' production LT1 style radiators now seem to come with a 1" core. Need to look at the specs before ordering.

Well, if you have LS powered vehicles to use 'em in, I'd hang on to them. :shock:

just installed that in my 97 LT1 a few months ago, fits great, great quality, made right here in NJ

I junked a nice used one a few months ago

I saw that one but also saw mixed reviews of it on LS1 Tech. Well, if the one in my car dies again, I know what to look for.
