I have a 91 360 roller block and no where to mount the crank sensor.

I have heard some of the early magnum blocks had PR oil holes drilled but none of them I have had apart had them.

It would not be rocket science to drill and tap a hole in the block and run it into the shaft, they do it all the time on big blocks for some reason.

I am not causing global warming, I am just trying to hold off a impending Ice Age!
