I certainly understand the OEM approach. But it failed. Like I said I have the Stock shroud, correct size radiator and fan. I tried the OEM route first... stock pump, clutch fan, 4 core copper and brass radiator, only when it failed did I go to aftermarket parts to try and correct the problem. The powerplant is by no means stock. Your suggestions are greatly appreciated. I will defintly reevaluate fan depth.
