Scott Drake 80006 High Performance Harmonic Damper 28 OZ

Compatible with 1963-1979 Ford 260/289/302. This product is not created or sold by Ford®.;

This damper is manufactured to match the dimensions of the stock early 1963-1969 small block dampers. The 6.4" outside diameter and the thickness are the same. The counterbalance weight matches the stock 28 ounce inches and the overall balance specifications are held tighter than the original O.E. tolerances. The dampers have both the early 3-bolt accessory pulley bolt pattern and the later 4-bolt as well. This will allow the use of late model serpentine drive systems on early engines if desired. This damper also includes three sets of 60 degree timing marks to allow it to be used on all small blocks. The counterweight for this damper is removeable, so if you want to build a neutral balance engine, you can use this damper by simply removing the bolt-in counterweight on the back of the damper.

Note: Use on 1970 and later engine accessory drive systems will require the use of a spacer for pulley alignment like #81006.;
