We bought this Ford Racing Crank Damper to use on a 5.0 with a Vortech in a 1987 T-Bird, but it won’t work with a blower. We added timing marks and installed it briefly before the blower went on, so we can’t return it as new. The car was never driven, just ran in the shop. It sells for over $275 in the Summit catalog. Feel free to email for details or for any other questions. Thanks. $150 shipped.
