I have two extra 273 rocker sets in the basement. All original, never been touched, that have the oiling as I described. I would trust "us" more than any "info". I have been corrected on things I never noticed myself by some of these guys and they were correct. I have loved high revving 273's all my life and have put many bigger engines to shame. There are reasons why they worked as well as they did, and their Heyday was 1967. I can also guarantee you, I never had an original T/A 340.
