The 2001's are making more power than both the pre-99 Cobras, and the '99 Cobras that had the fix from Ford to make more power. This moth's Muscle Mustangs & Fast Fords magazine tested out a new stock 2001 at the track & dyno, with very surprising results. With the nitrous, it'll be VERY tough to beat. Only one way to find out though....good luck!
