Thread: Radiator for 1930 Model A with Chevy 350

Tweet

Speaking from a lot of frustration trying to cool a SBC 350 with a brand new Walker '29 radiator, the soution was reached with dual electric fans side by side. One fan comes on with the ignition key while the other comes on in addition when a thermostat senses a high temperature. Several shrouds for 15", 16" and 17" inch mechanical fans were tried without success.. Initial success in cooling in February weather failed later the following July before the dual fan setup was installed. Even a brand new Walker radiator is marginal but i have heard of special (even more expensive) radiators that have a thicker core. The whole problem is aggravated if the hood sides are left on so some added cooling can be obtained by removing the hood sides.
