Engine Probs.

So 1 day after replacing the stock tranny with a 700e raptor i have now run into more problems. I have lost all oil pressure. My fluids have not mixed, nor am i smoking however i have a pretty grusem sound coming out of my top end. After oil drain I have found small brass shavings. Its not knocking so I believe my main and rods are intact is it possible that I have simply rolled a cam bearing reducing oil flow to the top end. I have not started since I heard the noise and lost pressure but I was over a 100mph when this happened. So being at that speed my engine rpm was high but as soon as I started to slow down my oil pressure dropped to zip. Any Ideas on what may have gone wrong before I hack into my engine?
