I have a radiator cooling fan from an 85 bird. Anyone know what the CFM rating is on these stock fans? Planning to use it in a friends engine swap.

 

im guessing it is a single fan, and not the dual fan? the cfm is rather low. i have one and it could never keep my 305 cool. i tried running it on my 4.3 blazer, and it didnt have enough cfm to cool that even under very low load. what sort of project are you doing? i have a set of dual fans for sale that came from my 86 tpi.

 

Thanks micro, I was thinking of using it for a v8s10 swap I did several months ago and is running alittle hot in town but ok on the open road. Dual fans did enter my thoughts. There are really good deals on ebay with 2500+ cfm but shipping parts to Hawaii kills us. Thanks for the offer, I'm gonna try local first. If not I'll send you a PM. aloha

 

my buddie got cooling fans off of tuner cars that used 1 so they were a higher cfm
took two of them and mounted one inside the bay sucking air in and one outside on opposite end of rad blowing air into the engine bay thru the rad.

he barely gets to 200* on a hot day with both fans on.

1 is constant the other is toggled
