Just curious, does anyone know if there are 1 or 2 knock sensors on the 496mag?
Starboard side I can see one easily, not so easy on to determine on port side.

There are two under the cylinder head.. port and starboard . Look for a stud and nut.
Question is why do you feel you need them. They will set codes if your running 87 or even 89 octane which is normal for time adjust during your key cycle.
Also poor connection, and pcm not seeing them can cause codes and a timing retard.
They are always monitoring so check after a 91 octane fill up.
Carry on and good luck.
