Then he should stick with the fan switch because you can turn them on while the car is off and it can at least cool the coolant in the radiator. Like I said earlier, $30.00 from SpeedSpecialty would get him a good fan switch, but like ZDriver said, TB bypass and a 160* thermostat is mandatory for LT1s as well. BTW Hypertech sucks.
