[LS short box]

Kind of disagree on the electric fan statement. You would be hard pressed to find a mechanical fan on a current daily driver. Anything with AC will have either two fans or a single two speed fan.
The key to making a electric fan live a long life is good wiring and quality relays. Also a quality fan maker. I always buy Spal fans. Never had a failure.
Just got done plowing the driveway with my 98 Wrangler with a LS6 swap. Did the swap 12 years ago? and the fan is still working like a champ.
If you think you might have a failure buy an extra fan assembly and keep it in the car/truck. I do that with the 255 fuel pump and never had to use it.
Just my.02.
