My mostly stock '90 5.0 is currently eqquipped with one of those rather noisy Flex-A-Lite flex fans. For about the same money I can replace it with a new electric fan and thermo-switch kit or a new stock clutch fan with March Power and Amp pulleys. Which combo would free up the most power? Despite test, most people agree pulleys make a descent gain for the money and the stock fan is probably more efficent than the flex fan. On the other hand, the electric fan is even more efficient and takes the weight off the water pump. I'd rather not pair pulleys with and electric fan for fear of charging issues. The car has no cooling issues to speak off (other than sounding like a Hoover on hard accel.). Any thoughts on which set-up is more benificial?
