Im considering putting on an electric fan to get rid of the belt driven fan. Just dont know if it will cool with my new motor. How many cfm's does the stock fan pull? What would be a good efan to use and how many cfm's? And how do I wire it, do I just rig up a switch to turn it on and off or can I somehow make it come on with the coolant temp? The new motor is a carbed 4.3l and the fan(s) needs to be able to cool up to 350hp. The computer wont be used but I'll have the coolant temp sensor hooked up for my gauge, thats all. Whats the best way to do it?
