I don't know about your 6.2 diesel, but my 83 C20 454 cools fine with a plastic/aluminum Spectra radiator. I have a SM465 transmission, but I think the Spectra radiator had provisions for transmission lines. I live in 115 degree HotZona and my truck never overheats, unless I have a bad water pump or leak somewhere.

The local A/C shop I took my truck to said that my stock oil cooler and DIY extra pusher fan for the condenser blocked too much air flowing through the condenser, so maybe you want to rethink the oil cooler.

I always bought copper/brass radiators but at around $500 now they are not worth the price. Those copper/brass radiators also sprung leaks every couple of years with only light use, so I like aluminum/plastic ones now. My radiator is only two rows but seems thicker than most tow row radiators.
