They were sort of a novelty. MF had a v-8 diesel so the marketing guys at IH decided they needed one too. They ran on 4 cylinders on light loads and all 8 under full load. I have heard if you were cultivating or doing something else "light" they would putter along on 4 and when you got to the end of the row, raised the implement, and stomped the inside brake to do a "bat turn" onto the next row it would kick all 8 in and things could get "interesting." They didn't have the "grunt" of a good 400 series 6 cylinder, and if you put turbos on them they tended not to last long.
That said, if that 1568 in the pics is a bona fide black stripe, it is pretty rare.
