ERSON Cams

[dpm68]

Hi. I am in the middle of a sort of rebuild on my 440. This is a 1969 350 hp mill and I have never heard or seen it run. It had to come apart because it sat for too long and has suffered considerably. I took it apart and found to my mild surprise, a double-roller with a Erson bumpstick stuffed in it. I would like to know if anyone can tel me what this cam is: ERSON TQ20 H 491. Any ideas?
