mgarblik,
We are definitely going to try another distributor. We've run the motor before without the belts..the knocking noise was still present. We did run the motor with the fuel from the bowls..I don't think we took the fuel filter off though. We still got the knocking noise with running the motor off the bowls. I can say that yesterday when we used a broomstick to listen for a signature, we definitely got noise from the distributor area but not the fuel pump. We will remove the fuel pump and block it off. We've removed the torque converter back 3 different times, the knocking noise was still present. We even installed a new flex plate and the knocking noise was still present. We've done the test of removing the plugs one at a time on 2 separate occasions and the knocking noise was still present each time. Also, the videos that I recently posted, the temperature was at 185 degrees.
- This video is the very first time that I heard the motor.

It's the video from the begining of this thread where guys reacted to the noise. There are plenty of other videos on my youtube page and they all sound the same.
ponchjoe,
It does not go away with RPM's. You can still hear it but it's masked with the sound of the motor. Not sure about the 12 volts. I'll ask my buddy thats helping me.
