FordMustang2000

I have a 2000 GT Mustang. The other night it started making a noise or knocking on the back side passenger side of the motor. It doesn't do it at idle only when you rev it up but when you reach high rpms it seems to go away. A video should be attached just let me know what it could be.

Sounds like a rod to me, pull the coil wire off one cylinder at a time rev the engine in between if the knock goes away good chance its a rod bearing
