OK we pulled down the fron of the engine last night. The original thrust plate did hav a 30 thousanths to 40 thousanths space between it and the block. I replace the plate. I'll have to check to see which hole the excentric was in.I hope that I have found the smoking gun. As I said before the chain and gears are new and sure enough thye are fine. I have both type timing lights and have the same problem with both. I wish I could have the car back together this week so I could post my results from the repair, but Im several weeks away from driving the car.
