Sensor locations on 360 magnum

I found some information from the Holley forum about knock sensors, and so forth (linked below). Also, found some indication that for placement, away from the valve train, and towards the bottom, back part of the block worked best. The other consideration was that the sensor should be mounted between two cylinders if possible. I looked at my block, and it look like using one of the holes that are for the mid style engine mounts might be a good choice.
