Unhappy Lets play...Name that broken part

I would post the vid but it would not be optimized until Christmas. So, if anybody wants to help, PM me your e-mail and I will send a video clip. The sound started after my run at the track. Goes away at 1800+ rpm but at idle it is very noticeable. I thought I had injector issues, I did, and that seems ok now but this sounds expensive. A very distinct "knock" from the block. Drivers side. The knock increases speed with rpm and slowly fades away as rpm builds. And the truck shakes slightly at idle. If you're ready to play PM me or reply here.
Thanks in advance.

whats your exact set up?

first guess would be a broken piston. #7 , thats just a shot in the dark since i dont know your set up but lots of threads that start of this way end up there.

5.3/Radix@9#'s/410 gears-Eaton/Built 4L65E/dyno tune.

I swear I hear some kind of sucking air leak down by the headers, and of course the knock. And yes this is a great excuse for a 6.0l also known as 408. Whatever it is, it's deep in the engine. I'll email the vid to you guys if you give me your address. It's onlt about 11 seconds long / 1.48mb

you might pull a valve cover and see if you broke a spring or something easy like that but i dont think it would run that well if you did. a pic of a plug might tell us something too.

Spark Plug from #7 The plug is surely not sparking! Its bent over on itself. WTF-O? Did the piston smack it or what?
