Engine/Trans Seriously Bad Noise

Okay. The trans/converter/flexplate/and bolts have all been thoroughly inspected and all checked out okay. Keep in mind this sound is very fast like a baseball card in a spoke wheel. Not a slow ticking. It also follows the rpm band. So now that the trans and parts are ruled out. I'm going to drain/strain the oil and cut the filter and look for metal. It also has been suggested that the spot welds on the windage tray may have broken loose. Again, this motor was dyno'd and run through several pulls. I realize that things go wrong but I'm of the thinking that if anything bad was going to happen to that motor. It would've on the dyno. Also, all the spark plug electrodes look just fine. No damage. And they're long reach plugs in aluminum heads. It never hurts to check, but I just find it difficult to be the engine making this ridiculous noise.
