If used on a 4V engine, the accessories (alternator, A\/C, etc) will rotate 3% slower than stock. Normally this is not a significant amount. This is due to a slightly different diameter of the damper. These dampers do not have timing marks on them but do have a notch in the back rim of the damper indicating TDC","brand":"Professional Products","offers":[{"title":"Default Title","offer_id":46059431657532,"sku":"80020","price":104.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0632\/5934\/4956\/files\/80020.png?v=1787699026","url":"https:\/\/rpm-racing.com\/products\/6-9-pontiac-v8-326-350-389-400-421-428-455-1961-79-harmonic-damper","provider":"Racing Precision Motorsports","version":"1.0","type":"link"}
