In other words, if you have a 17" fan and it's a quarter inch away from the Radiator, you're only using a 17" circle in your radiator to cool your engine.
On the Flex Fan. It should work just fine for the symptoms you have described. A "Flex Fan" is designed to flatten out as the fan's rpm increases and to pull LESS air as it does. [quote]

I had a flex fan on a 331 SBC and was racking the throttle from beside the roadster. The fan blades flexed foward and cut into the radiator. Thankfully I was sprayed with warm water, not hot!! :shock:
