Another Small Block Crank Damper question

Thx guys. I've seen many of your other posts in the past and it's great to hear from so many of you that have "been there, done that." And so many of you have cars that are just awesome!! Nothing like the real world experience you have and that is what I enjoy and appreciate the most about the FABO site. Looks like we run the gamut here on what has worked for dampers. I ran the stock damper on my big block 69 Charger for years - 383 car and then 440. It lasted about 10 years shifting it at 6800 (383) and then 6300 (440) until it finally spun the outer ring. Looking forward to see where this 408 small block will want to be shifted given the longer 4" stroke.
Again, appreciate all the input!
