Randall,
Please tell me if this is wrongheaded thinking.  First I bought the  12" fan 
because *they* said is was the correct one for my car.  Going past  that, the 
stock fan (yellow plastic not stock/stock) is 12" and has 56 sq in of  blade 
area and the electric has 42 sq in of blade area.  Both fans have  similar 
pitch.  Can't tell you the degrees as I just lined them up with a T  square and 
didn't go for the protractor.  The electric has a more  *efficient* blade 
configuration, but this is where I think  the electric is superior.  The stock fan 
is limited to the air  movement by the rotation of the engine at idle.  Let's 
say 800 rpm  whereas the electric is 1800 rpm.  Will I not get better results 
from the  electric for the same diameter fan considering the 25% reduction in 
the blade  area?  Am I just plain dumb for not putting on both?
