1969 Z28 balancer

[dvss1]

Hi, maybe some of you guys can help me out. I have a real nice what I think is a z balancer but it has a m-c and s-2 cast into the outer ring. Has anyone ever seen this? I looked at my 3 z28's and none of them have this. I even took a mirror and looked on the back of them. None of them have this. I would really like to use it since it has no hammer marks and one that is on one of my cars looks like King Kong got a hold of a hammer. Thanks

Good evening David,
I am almost positive that is a 1970 LT1 balancer. To be 100% certain you may want to ask one of the 70Z owners what their's looks like.

Dave, Is the key way in line with the timing mark? Sam

Hi, no the keyway is not inline with the timing line.

I believe the 69 was a one year style. The Y where the pulley bolts stands by itself with no ring around it.
