Are you going to put the fans on the front (pushers) and run the fan on the water pump also?then a shroud is ok.If you are going to m ount them as pullers (engine side of radiator) then no shroud.
Aternate the posistion of the fans you know top left - bottom right or top right - bottom left. Diagonally works best because you can cover more area. put them closest to the water inlet and to the outlet.get the most cfm fan you can fit in there.I dunno, do they make a full shrouded electric fan setup that isnt like a one motor one blade oem pos?Something with directional flaps that would allow airflow while moving and not while at a light when the fan was on?

Whether you run the fans as pushers along with the WP fan or as pullers (most efficient), you need to have a shroud, either as part of the electric kit or OEM/fabricated.

Find a Lincoln Mark VIII & get the fan or new on Ebay. These work better than most all aftermarket fans. Intrepid fans work well also.

Even the best fan is not going to do well without a shroud.

Check out an HHR fan setup, they are pretty cheap for a dealer part and pull a ton of air. Lots of big block mopar guys use them. I think the whole deal is not much more than 5" thick but please don't quote me.
