If I find out anything from the dealer (waiting for them to call me back), then I'll post up. I might take it to them tomorrow anyways just for a peace of mind. If it turns out to be normal then I'll gladly move on and enjoy the truck (which I'm doin', it was tough leaving it at Ziebart this morning!).

I haven't popped the hood on any other 6.2's and my 2v V10 was never that loud so I really have nothing to compare it to.
