I run a Champion radiator on a PU and works well. I run it with OE style shroud and mechanical fan (Ford).

I do not think that fan setup will make you happy. Running down the road at speed the shroud will block airflow. At a stop the fans will not pull enough air. A bigger OE spec single electric can work well. Ford Contour, Lincoln Mark III and Chevy HHR are some examples. I do not know about fit in your application.

I am sure you already know an effective electric fan will require upgraded alternator and wiring. Plan on a steady draw of 25-30 amps for a fan with enough airflow. Peak draw will be higher at startup.
