I ran a CS130 and Lincoln MK8 fan on my old 454 truck. That was when I lived in TX and it happily ran at 205, a/c on or off all summer.

I may go with an explorer dual fan setup on my current build.

I also have a CS130 on the caddy, but no room for an e-fan

Any internal regulator alt will work, and generally give better output than stock. I'd avoid a one wire, that's not the best way to go. Madelectrical.com has some good reading about this.
