Rattling?

Rattling?
Ok, I have heard this rattling for a LONG time in my engine. I mean it is the WEIRDEST sound almost sounds like a connecting rod is vibrating or something. I know that some engines just have certain "design" sounds, some rattle etc. But this sound really kinda worries me. I was under the hood this morning and was doing quick revs and it seems to do it the loudest when its winding back down from high rpms. I placed my hand on the alternator while it was idling and you can even FEEL the rattling, it may be just one of those design things but I am kinda worried about this!
Anyone else who has an LN3, give me your thoughts on this!!!

I've got it too.... no idea what it is. kinda concerns me too, because i think it'* kicking the knock sensor on and pulling timing. May not be a bad idea for you to scantool your car wj... see if you have the same thing.
And it'* done this since i've got the engine installed 250mi ago. So who knows how long before that.

You know I'm actually wondering if it really only is a noise of design.
Umm...well I don't own a scantool, but the last time I had one on there I was showing barely any knock...maybe a couple points at 3/4 to WOT, but that was about it. and this noise obviously existed at that time. But yeah, it kinda does sound like pre detonation.... :?
I'm confused.

Mine sounds like metal on metal... like if a main bearing didn't have oil on it, that is what it would sound like, and it'* the most obvious coming down from 2k w/o load. It'* only there on the decel.
Do you know what the total advanced was?
