Well...
Rich,
While what you did would absolutely work with an engine already together (as long as it wasn't cranked any.) When you assemble and engine from a bare block and crank you need to be able to set the crank at 26 deg ATDC in order to put the CAM Sensor Assembly in correctly. Its in Haynes, the Ford Manual, Chilton, etc. Its only needed that one time because you don't have anything to reference it from. It also take a special Alignment tool to hold the outer housing tight with the inner Vane. When I get some time I will scan the procedure from the Ford Manual and Photo the cam alignment tool.
