This damper is dimensionally identical to the stock G.M. 6-3/4" damper & our damper has 60 degrees of timing marks engraved!

  • Notes: Chevy Small Block engines have used three different timing pointer locations. Pre '69 engines have the TDC mark 2° to the left of the keyway centerline. The '69 to '85 dampers have the TDC mark 10° to the left of the keyway centerline. The 1986 to 1991/1992 have the TDC mark 40° to the left of the keyway centerline. All of our SB Chevy dampers, as well as all other aftermarket dampers, use the 10° TDC position. Our 6.75" diameter models have two TDC marks, one that is 10° and one that is 40° to the left of the keyway. If you have a pre '69 vehicle you can use one of the aftermarket bolt-on timing pointers to align correctly with the timing marks on our dampers.
