Dale,
I was going by the picture of the Racing Beat block-off plate. The picture shows the cross-drilled passage plugged with what appears to be a 1/8-NPT plug. If installed on a 20B and left plugged, you would not have oil supply to the mains. You could also have a problem if you installed it using a 1/8-NPT x 6-AN fitting in order to use it on a 20B. This wouldn't be a problem if used on a 13B with the factory oil supply fitting in the lower end housing. My 20B adapter is very similar to the Racing Beat adapter, except I welded a -8 AN bung which is connected to the outlet on my oil cooler. The ID of the bung is the same as the diameter of the cross-drilled passage.

Mark??

   Ummm, perhaps I missed something, but didn't the block-
off plate have a drilled cross-over between the o-ring
cavaties? The one I'm building does - as well as a port
for oil pressure, and I could put in another for oil
temp. ( that part is a little more complex, because there
has to be a cavity large enough for the oil to wash over
the sensor) in case anyone is interested.
