Description

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 model shave 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.

Although this model damper features a bolt-in counterweight, the damper cannot be used without the weight. Due to the windows cut in the front face of the damper if the counterweight is removed it is still not a neutral balance damper. If you need a neutral balance 6-3/4" damper use #80000 or #90000.
