Default What CFM do I need???
I am looking at a set of Electric Fans... they said they move 2780cfm..

They are 23 1/5inches..... Will these fit... and if they do Is that enough air for my engine...

I have the 5.3

My radiator is 28.5inches!!

Are you saying that each fan is 23.5" in diameter or both fans together (or the fan unit) is 23.5" inches long?

is the 2780cfm for both fans or the rating for an individual fan?
