1969 Dart Street/Strip (Re)Build

Well it seems that I can't catch a break no matter what I do. Came home from work yesterday and started the car up to take it to a show. I let it warm up as I was putting the GoPro on the window. When I got in something sounded different like almost a grinding type noise. It wasn't "normal" to what I have been hearing. So I got back out and I hear knocking coming from the motor. It was hard to tell where it was coming from. It almost sounded like it was coming from the passenger side so I popped the valve cover off and didn't find anything. So put the cover back on, started it, didn't hear it anymore. Thinking maybe it was a fluke I pulled it out of the garage and it came back. I could really hear it now. Sounds like it's coming from the bottom of the engine. Oil pressure was good. So I parked it and opened the oil filter today. The oil had quite a bit of sparkle to it which is to be expected since it's fairly new but unfortunately the paper was torn open in one spot and I found a few metal shavings in the paper as well. I think the motor may be done already. This is quite upsetting. I think it my be time to find a new hobby.
