Odd Knocking Noise

I recently installed a 351c into my truck it ran perfectly for a few days until now, its started a horrendous knocking... the torque converter bolts and the inspection plate for the torque bolts were loose so i tightened those down, i dunno if they are loose or my main bearings in the engine are shot.. any clues??

try unbolting the torque converter and pushing it into the trans far enough to clear the flywheel and start the engine see if it still makes the same noise. JOHN FATFORTY

well another idea came to me, i adjusted the timing and you can also hear a loud valve train rattle, the engine isn't exactly new but its only got 55K on it so everything internally should still be fine... could the timing cause this noise *knocking*??
