I recently finished an engine transplant in my '69.  ( see engine forum for particulars ).  As part of the surgery, I installed a BeCool aluminum radiator with the dual electric fan package.  The motor is around 480 flywheel HP and I have yet to see the temp go over 190 regardless of outside temp or traffic conditions.  If it is under 85 degrees outside temp, my fans won't even come on until I stop for anything longer than a red light.  I have only seen one fan come on, never both.

  I have to say, this is one of the best investments I have made in any car I have ever owned.  Now if BeCool would send me some money for plugging them, I would be a happy man  .
