Tick noise at high rpm

Hey guys just wondering if you guys mite know what it is. When I wot as soon as it hits 5,000 rpm I start to hear a tick. I have 1998 SS m6. Not sure what it mite be. Can it be that one of my springs in my head can be broken? Or it's a spun bairring ? Any suggesting would help.. Thanks

If that's the case then you have a spun rod. My case is a Lil diff. I only get the ticking at high rpm.
