And being a Magnum balancer, make sure you've got the right timing mark- confirm by finding TDC on #1. Both Magnums I have in my shop right now have 3 different timing marks on each balancer, only 1 is for ignition. The other 2, I believe, are for crank sensor and EFI calibration.
On our '01 Magnum it had a mark that lined up with TDC on the drivers side timing pointer, and another mark that lined up with the older passenger side pointer at the same time!!
