Not a dumb question at all. If I was going with a mechanical fan then yes or even a single electric fan, I would use a shroud. But I'm looking at dual electric fans that have the built in shroud that covers the entire radiator.
My problem right now is the size. The radiator isn't for a 56, not sure what it's for, it was sold as a 55-59 and I go it real cheap but it's new and aluminum so I plan to use it. But the radiator itself is 25 1/2" wide with 1 1/2" mounting bracket on each side for an electric fan. It's 16" tall for the core area and 21 1/4" overall high. The problem is the distance between the radiator and the bolts on the water pump pulley, I only have 3 3/8" between the 2. So far finding a fan that will fit is a little tough.

I agree, 1600 cfm seems a bit low, bigger better IMO (in most cases)
