Unknown noise coming from engine

[Bryan]

Getting this noise from the engine in my 92 SHO and I don't know what it is. Well that's not entirely true (I think I have an idea), but I figure I put the sound clip here and see if anyone can't tell.

Do you have one of those stethoscope probes from Harbor Freight to narrow down the sound in the engine, a long screw driver works too
