I have the same pump from a 96 bus. When I sent my pump to Seth the internal timing was set at 12.5 degrees and not 15.5 like the timing cover said. Seth was able to max and balance my pump at 500cc. If I remember correctly these pumps can not be set by using a dial indicator on top of the plunger. Can remember why but that what Seth told me.
