I found out last week that the bronze distributor gear on my MSD dizzy is stripped. I have a HV oil pump and I had changed the oil about 500kms ago to Mobil 1 10W-30. BTW, it's a 351C 4V. Changing the oil to synthetic wouldn't have had anything to do with the stripped gear would it? I'm hoping it was just a coincidence but I did notice that I picked up some PSI on my oil pressure when cold.
