I hate to introduce myself like this, but here goes. I bought my car in all sorts of disrepair on ebay. I've been working on it for several months now, and its finally running. I got it on the road monday, and i'm having a few problems, mostly electrical (car has minor flood damage). The most serious though, is what sounds like a pretty nasty knock. I am by no means and expert, but I certainly need the aid of one. I'm including a video of the noise I get under high revs.

The video is not great, and I did it in a hurry. You can hear the rattling sound on the second time I throttle it.

 

The video is hard to hear with (but my hearing isnt too good sometimes)...Sounds like a knocking to me....Time to start some tear down and see what is making the noise.

 

Bump, maybe I can get some more help with this.
