IMO electric fans are another of the race car items that are best left on race cars. From experience, it's a whole lot easier to find a replacement fan belt than it is a replacement cooling fan when you're miles from home and just cruisin' on a Sunday afternoon.... I have learned over the years to try to keep my cruisers as cruiser and race cars as race cars. A good mechanical fan with the proper shrouding on a well tuned street car will do just fine in the cooling department. Trying to maximize the horsepower on a street car usually results in something that becomes a pain in the butt to tolerate!!!

The absolute cheapest horsepower increase is making the car lighter!!!! There are many ways to make a car lighter if you do a bit of studying and checking the car over. If it's loaded with sound deadener, insulation, and undercoating remove it... Many pieces are just plain unnecessary on a car that is being used for a bit of "street sport" action... A donut spare weighs considerably less then a full sized spare, etc, etc. On a BBF, a $40 swap meet aluminum intake weighs about 12 pounds less then a cast iron one. I probably couldn't show you 1 place to take off 100 pounds on your car, but I bet I could find 100 places to shave a pound. On the dragstrip, 100 pounds less weight equates to 1/10 of a second lower ET!!!!
