Detonation is the spontaneous combustion of the end-gas (remaining fuel/air mixture) in the chamber. It always occurs after normal combustion is initiated by the spark plug.

Pre-ignition is defined as the ignition of the mixture prior to the spark plug firing

Why is your vortec 5.0 knocking?

It could be: A. worn rod or main bearings. If that's the case you'll have low oil pressure. B. a faulty "knock sensor" that's supposed to retard the engine timing when it detects early ignition detonation.
