Be we know it does not.
Knock sensor has to match knock filter whether it's in memcal or ESC... and the sensor has to be for engine. So your point of V6 knock sensor matching V8 because of bore and stroke is valid. We started to collect info on this but there were so many GM numbers I don't think we ever came to a conclusion.
