when Ford put out the 94 Cobra [car of the year]...why did it not make it faster than the z 28,and why only a 308 rearend, which everyone is replacing with 355s and 373s,,,I am curious,it seems like I have to do alot of work to mone to make it comparible to my 94 z...could thier svt team have been so much off the mark,correct me if I am wrong. Thanks
