I love Jack and Judy. This is one place where my dear friend and I disagree. If the roll pin has lasted 132,000 miles without failure its not going to fail.
The roll pin failures are a result of installation of the "non-original" heavy duty oil pump shafts ... period. If your car's engine is equipped with a standard oil pump drive shaft, the standard roll pin is not going to fail. Its a well engineered system. How many millions of Ford vehicles have traveled more than 100,000 miles per vehicle without failure of that roll pin? Without stranding the drivers and passengers? What has the last 132,000 miles taught you?
If the 351C has original valves, that's a far more precarious situation.
