The knock sensor is to detect detonation, which occurs in the upper
combustion chamber. Knock sensors should go on the heads.

But what good are knock sensors unless you're using electronic
ignition with variable timing? Is that what the OP is using?

Yes , it will have adjustable timing---, and, due to a fortuitous
acquisition of some mixed parts--(all new) a fairly high comp ration--
hence the need to monitor detonation if it occurs. Jerry
