i have a spare ati super damper that came off my motor when i got it rebuilt. i cant figure out what balance it is for. the inside of the hub has a 916562 printed on it. also on the back is a 916902. front of the balancer says its a zero balanced damper, but my motor wasnt zero balanced. it also has a weight on it with the numbers 850 on it.

any help anyone?

 

A stock 89 uses a 50oz balance. If you look at the backside of the balancer, is there a bunch of metal in one section and a void around the rest? Was that balancer on your old stock block/crank? If you see the offset metal, I would wager that it is a 50oz

this is an aftermarket ati damper that was on a fully forged 347 stroker. anyone else?

 

if u can confirm its a 50oz, ill buy it off you if you wanna get rid of it..
