I live in Phoenix where the summers are HOT. I have a 2 row Griffin Al radiator. Works Great! Prior I lived in LasVegas,Hot there too. The radiator was a direct bolt in. I use the stock shroud. Looks good too. I need to get an electric fan (Maybe Hot Rod Air?) because in the winter I have to put a small piece of cardboard in front of the radiator so it will get to operating temp.
