My 78 bronco has a 71 lincoln 460 punched out to 466, I have the stock radiator and presently have a flexfan in place. I am dropping the flexfan idea and going with an electric fan to save HP and have the ability to shut the fan down. My question is, should I go with a dual fan or a big single? Is a 14" fan big enough? Thats the biggest I could find on ebay. Are the ones on ebay not very good? What are the best ones to get? I know it's only a fan but it's still important and I told myself a long time ago, don't go cheap on your parts, get quality stuff.
