mrmustang,
A question if you please. As I stated above I don't know a lot about Mustangs as I have never owned one. But a couple of my friends have 68 GT-500s and they have 428 engines in them. Also, watching the show about the Super Snake, 427 Mustang that they built which was a one off, the Ford engineer that was attached to SAI at the time made a remark that they just took one of the GT-500s, pulled the 428 out of it and then had to completely rebuild the drive train to take the LeMans 427. Also in the same show the man that was the SAI sales rep in L.A. at the time said that a high ranking official from SAI had come to them and asked them to do a survey and see what people would think about having 427s in the GT-500s instead of the boat ancor 428s they were using. As he said, for obvious reasons he wouldn't name the official, but he had Shelby's consent to do this. I knew the KRs used the 428SJC engines, but I haven't seen a 500 with anything but a 428 in it. However I haven't seen a lot of the 500s either.
