La parts on a magnum

Not the lifter ticking?
Everything heads down can be put in a magnum block.
All the magnum bottom end weights are different but swapping rotator and balancer as an assemble is fine. Magnum timing cover work work either

No i dont belive it is a lifter i have put 2 new comp cam sets on it and the tick is still there. But that info on the parts swap is helpful thanks.L4staero
