How much CFM does the stock 1998 vs the 1999\'s and above fans pull?

I know the newer ones pull more CFM but does anyone have any idea how much?

On that note...

I am thinking about upgrading my 98 to a 99 style fan... should I upgrade to the aluminum radiator as well?

That's what I am planning on doing but thinking of fabercating a shroud that has a fan that can pull more CFM than the stock. I just need to get a reference of what the stock ones do.

Not sure about exact CFM numbers, but I do know that one of the benefits of the 99+ fan is the placement of the fan, and the diameter. The motor is also smaller but stronger.
