Engine is a LS3. When I got my engine back from the shop the stock balancer was off so I do not know where to start on lining up my ATI one. Do I need to line up the timing marks and if so how do I do this? Im assuming I line up the cam gear with the timing marks on the ATI balancer somehow. Ive searched and searched and can't seem to find the answer.

 

Ooops this was supposed to be in Gen4 not Gen3 section

 

The marks on the balancer don't mean squat.

 

yup, don't even pay attention to it. I run an ati super balancer. just chose a random place to pin the crank and got ir dun. The only important things to line up are the cam and crank gear.
