Cooling fan specs?
From what i've read S blades cool less but are more quiet than the straight bladed fans.
Dual spals supposedly fit with the ATI set up, they flow at about 25-2700 cfm.

The stock fans are surprisingly good air movers and the stock shroud helps with the combo. I think they are in the 2,500-2700 CFM range for the dual setup.
Straight blade fans move more air at a given speed and same number of blades than curved blades.
The Spal fans tend to be among the best. I think BeCool resells the SPALs. They have thin medium speed (2.5-3" thick) and slightly thicker high speed (3.5" thick) models. Those can come with the curved or straight blades and in pull or push setups. Always use Pull Fans for the most efficient movement of the air across the radiator. Mounting a push and pull combo is not as efficient as a dual pull setup.
You're looking at dual 11" straight pullers (in the 2,700 CFM range for the set) to replace the stock setup. You could get dual 13" cruved pullers or 14" straidth pullers (1,710 or 1,720 CFM each) in there with a custom shroud setup.
Some will run a big 16" fan (around 2400 CFM for medium profile line and 3,150CFM for a 4" thick high speed straight blade) but I'd rather have the duals myself and move more air over a bigger area.
You can see the models at BeCool's website http://www.becool.com/products_fans_puller.cfm to get the demensions of the units. Then take a look at summit or jegs to see more stats and pricing.
Here's another site that sells the SPAL models directly but you'll want to know the model number before you go shopping or give them a call to disucss your plans:

I have it pulling, works fine here with the summer heat on a stock radiator, rarely gets over 205 sitting in traffic and comes down quick when moving. I have no a/c though. I was going to make a fancy shroud or do a couple pushers + this one but it seems to be doing OK without it. Its not as good as the stock fans but it works for me, I only put about 50-100 miles a week on the car though. Probably wont do that great as a pusher.
Why dont you think that it would work that good as a pusher?
I have a griffen rad, that is dual core, I think between that and a nice sized fan it should work. I think that I could actually use it as a puller as well, since I moved the rad forward
hmm
thanks

I never had good luck using a singe electric fan as a pusher on anything. Its marginal on this one as a puller so i would say it wont cut it on a stock radiator as a pusher on a street driven car. It may work with the better radiator though - one way to find out
