A little over 2800 cfm, aint enough for a hot bigblock stroker --------------

I just took off 2-10" fans with shroud rated at 1750cfm each. Wouldn't keep my car cool at all. A 4 mile drive i was up to 230 degrees. I put my mechanical fan back on and in 10 miles it never got over 200 degrees in 90 degree weather.
