This is an original high performance harmonic balancer that was removed from a 1968 Z/28 MO 302 engine. I believe this balancer was specific too 67-68 Z/28 302 engines and 67-68 327 L79 engines. This balancer has been glass bead blasted to bare metal as shown. There are some isolated areas of pitting and some hammer marks are shown. This is a very nice original part overall. $350
I also have the timing cover off the same engine for $175.
Thanks,
Jason
