The 260 and the early 289s (first half year run) had a five bolt bell housing. Since then all 289s, 302s, 351Ws, 351Cs, and 300/240s have run the same 6 bolt bellhousing bolt pattern. There were at least two bellhousing though one to clear the smaller flexplates and one to clear the 351Cs and 351Ws on the C-4s. I believe all C-6s had the room in the bell to clear the larger flexplate. Not sure on that part though.
