Damper is ordered. Went with the Mopar Performance SFI one. It was a little more expensive than the aftermarkets available but is getting here next week instead of 2 months away. Thanks to yellow rose for the offer he gave me. Appreciated.
I wish I saw this earlier. I was planning to put a blower on a 392 w2. I added Molnar rods and had it rebalanced, I had a second keyway added to crank and a second keyway added to 2 different balancers because I wasn’t sure about spacing or which one I was going to use. I have a Tci rattler and an Ati super damper, both double keyed.
