All I. An say is after a few electric fan set up that I have tried, I'm sticking to the factory Viscous fan with a shroud!

That's because MOST electric fans are play toys. Until you approach or eclipse 4K CFM, you're really not doing a performance V8 any good. Most people don't want to spend the money on a REAL electric fan. I don't really blame you. Cause I don't either. lol
