I have Ford Contour fans on the 5.7L Hemi and they will cool the car in Texas Summers on low speed.

I run the fans on high speed when the a/c is on and they move a TON of air. Ensure your charging system is up to par with any of the solutions out there. I'd really consider using a PWM fan controller, if I were you. Yes, those are "electronics", but they are very effective for managing electrical loads.

I had a HHR fan with the 318, which also worked pretty well.
