this is just my opinion--and you know what they say
about that........
i have never found ANY electric fan ( single or dual )
that will cool my motors. granted, they are a bit nuttier
than the average guys build
-current is a 10-1, 461" with a 292/.595/108 cam-
but still...
and i tried 'black magic' fans, taurus SHO fan, lincoln
MKVIII fan, viper fan, twin 16" pullers, etc...
my standard 'go to' fan is the 18inch black plastic
flex-a-lite # 418 in the stock shroud.

it move some air!
it keeps my motor on the 180 t-stat even in 2 hours of
93 degree heat stop and go, bumper to bumper traffic.
not to say my feet arent cooking in the car, and i am
sweating like the pig that i am, but the motor aint
overheating!
your results may differ, just letting you know MY personal
experiences with electric fans.
