REGAL Electric fans worth it on stock engine?

For an aftermarket setup, yes. I was merely offering up the manufacturer's logic with respect to airflow vs speed. If you're overheating at speed and the fan comes on, you're not going to stop overheating.

I'm not hikacking a thing, I'm providing facts so anyone who reads this can make an informed decision.

I went with OEM factory dual fans with shrouds. one from a 1999 Malibu, and the other is from a 2000 Buick park Avenue.

Here is a wiring diagram I made for dual fans. It runs the fans at slow speed with Key on. This only draws about 6 amps. Because the fans are already running at slow speed, the switch to high speed doesn't spike the amps like hitting dual fans from a rest would.

Chrysler 300M/Intrepid fans are cheap and plentiful at any U-pullit junkyard.

He may not realize the benefit of the electric fans now. Or only a small amount, but if the OP is going to go LS at some point, it will be another thing that needs to be done at that time, so why not do it now? I would, and already have... JMO

Any car with A/C I would switch to electric fans, even if it only had 110 HP. In the summer with the A/C on you'll feel the difference in power, especially with 3.55 gears reving the motor above 3,000 RPM when passing.

A locked up clutching fan takes the same HP above 3,500 RPM on a 110 Hp motor as it does on a 350 Hp motor.

No reason not to if you’re going to LS swap it in the future and he doesn’t need a setup in hand by Monday morning. Plenty of time to find good used parts.

With an LS swap, you can have the "Fan on" relay ground through the LS computer "fan on" wire and set the fan on temp in the computer to what ever the thermostat is.

That would make the low speed fans come on when the thermostat opens and switch to high speed when the 195 deg switch grounds.

Don't LS computers have high and low fan outputs? The ones I've seen do.

Correct,, but on my 2000 Yukon XL I had to add a new wire to the harness. A harness from a car with factory fans should already have that wire.
