Swaped them to the 2.97 2.07 1.43 1.00. First gear would be almost the same as the 2.66 first gear with 4.10 in the rear, and from what everyone says 4.10 are awsome. Why would ford put a close ratio trany in a car with such a broad power range. Also from what i have seen (doesn't mean it will happen) the 07 gt 500 will have the 2.97 gear set.. I dont think it would be too hard, people already swap the 5th 6th gear set.
