I have always thought my 440-6 was poor alignment. If you are familiar, the 70 B bodies came with that dammed "scalloped" clutch which puts the disk edge in very close proximity to the mounting ears. "Any" little fuzz on the outer edge of the disk will drag on the ears and not release clean. That thing never shifted all that great and seemed like every time I had it apart, the pilot was worn bad. I'm am not a guy who sat in traffic with the clutch released
