Cold Case 26in Rad fitment

I will eventually like to run an aluminum radiator in my 73 Valiant, and even more when I build a 408 Stroker. What is the best close to bolt in setup that can run a factory 26 rad shroud with maybe a flex fan since the Hayden low profile clutch would not work with a champion or CC radiator. I defiantly do not want to run any electric fans. See cars that cruse at the cars and coffee that have electric fans and its not a great sound when it overpowers the engine.
