Knock Sensor Question - Ferm/Spare!!!

[spareparts]

story goes(it was in Hot Rod)some guy was talking to the Cadillac engineers about the starter in the NorthStar engine and how stupid it was to mount it in the the engine valley. The Cadillac guys stated that the starter in the Northstars had the lowest failure rate of any of the GM engines and they had engineered it to be almost infallible. The guy asked them why the did put that starter on all the other engines if it was that good, the engineers didn't know how to answer
