Did you change the springs or the advance stop bushing on the MSD Distributor you installed? What is the part number on the MSD Billet Distributor that you have? Do you have a degreed harmonic balancer or a degree tape on the balancer?

The PN 8456 does not have spring and bushings, it is a direct replacement distributor and the timing is controlled by the ECU. The timing is adjusted the same as a factory where you disconnect the PIP Connector and check base timing. I do not know what total timing would be; you will have to check it on the vehicle.
