I'm going to be replacing the radiator on the chevelle soon in order to get ready for the AZ summer. All the local guys are telling me to get a fan shroud for the current engine fan and itll keep the engine much much cooler. It currently just spins in the engine bay without airflow direction. I'm contemplating picking up and aluminum radiator and throwing dual electric fans on there at the same time. The motor is a fairly aggresive 327. Whats the better choice? Will an electric fan or fans keep the engine as cool as the normal engine fan with a shroud installed? Any advice appreciated. Thanks.
