Well, the factory Chrysler radiators are a different animal. Their cores in the 3 and 4 row are high efficiency cores. They have more fins per inch than the standard radiators do. All these China radiators don't. That's why I TRY to advise people against them. They aren't ALL bad, but it's a crap shoot to get one that SOMETHING isn't wrong with, whether it does not handle the heat transfer or something doesn't fit right.

When I was in the Air Force, one of the guys in the barracks needed money and wanted to sell me his 71 Polara 440 car that used to be an Arizona Highway Patrol interceptor. I got it for $200! It had a 4 core radiator that I immediately put into my 69 Charger 440. The day after I bought it, the guy and his friend were camped on my doorstep begging for that 4 core. He had a 70 Challenger 440 and needed the extra cooling. Great memories!
