Electric fan hookup.
I just installed a flex-a-lite 110 in place of the clutch fan and wired it together with the factory aux fan on a toggle switch. Works really nice in cooling at low speeds and I have total control over the fans. I installed a flowkooler water pump, throttle body spacer, new 3-row rad, and banks header and am probably pushing 210 HP; however, the thing still overheated (boiled over at 260*) going up to the sierra's pulling my boat in 78* weather. If you want to run this, make sure you get a 5 prong relay that allows you to hook each of the fan positive wires to its own prong on the relay. That way if one fan breaks, you can still run the other one. The good thing about that dual fan setup is that it'll cool a 240* engine down to 190* in 5 minutes. The bad thing is that it doesn't push enough air to keep the engine cool all the time. I'm convinced that I can't lick this overheating thing.
