According to the notes that came with my car from the previous owner, the proper count is 157-tooth for both 260 and 289, five and six bolt bellhousing.

The document goes further to say that “large 164 tooth flywheel (commonly found on pick-ups) can be used with large cast iron bellhousing which has provision for narrow trans. pattern at a significant weight penalty.
