Is there an advantage to one over the other? I am running a 350 SBC in a '57 3100 as a cruiser that ends up sitting still for extended periods of time due to traffic [Woodward Dream Cruise]. Have not had any issues so far, but the orginal radiator is on its last leg with a missing over flow tube, and what appear to be small deposits on some of the vains of the radiator that I assume indicates microscopic leaks?
