fan cfms?

I am thinking about getting electric fans for my 02 4.3 silverado. Does anyone know how cfms the stock fan puts out. Ive read about the flex-a-lites pushing 2500 cfms. I live in austin tx and it is hot so I want to be sure about the cooling capacity before I spend the money.

If you want to contact me tonight I can show you the LS1 fans and the '05 fans in action. I live in Round Rock. I am leaving Friday morning for 3 weeks in Montana, coool weather. Email me.

Hey jethro I actually live in Round Rock also. That was something I was wondering if anyone has used the electric fans around here. Id love to take a look but I cant tonight, maybe thursday or when you get back.

Thursday after 5PM I will have a few moments. Brushy Creek. It won't take long to see what I've got....
