I believe that the car in the Motion "Wanted" ad has an SS stripe on it.
Motion AD
I think I have a test eport on that car somewhere, let me know if you want it posted.
I noticed too that there seems to be a conflict in the article, first saying 427-425, and then saying PhaseIII, which should be more HP. But these old articles almost always have mistakes in them, sometimes huge mistakes. For research, the pictures are probably more valuable. The story is good reading, espicially the story telling, just like BSing with friends. I like where he says Joe was never beaten. Riiight. Another example, I don't think I am 100% sure that the car really had rear disks, since no picture showed them. Take it all with a grain of salt, but it's still a good article.
