We use ATI super dampners on our builds---for the ford FE the bolt pattern on the dampner is for a bbc and you'll need to offset drill the pulley holes .050 to use original pulleies---if you want to use later or aftermarket just use with a chev bolt pattern

The dampner that I would stay away from is the fluiddamper---every time I see a broken crank it has a fluid dampner on it---

Have you got back to the 767 yet???
