Hey i have a question, when i bought my 94 Cobra the previous owner had put the March Underdrive pulleys on it. I've also read that from the factory the Cobras had different pulleys to begin with. Are the March Pulleys better anyway and should i just let it be or should i swap back to the factory cobra pulleys which i also have with the car. Thanks alot any help is much appreciated.

Since you have the aftermarket ones on, I'd leave them, unless you are having cooling or charging problems. You will get a few horsepower from aftermarket underdrive pulliesn on a 94/5 5.0 Cobra, but not nearly the jump that you would get from adding them to a GT, because the stock Cobra ones are slightly underdriven from the factory.

Keep the March pullies...just look at the size difference of the crank pulley(where 90% of your power from pullies comes from). The March should be waaaaay smaller....
