I also forgot to mention that the last time we pulled the motor (Right before it went back to Arizona), we noticed damage to the oil pump shaft (Witness marks- I posted the pictures earlier). We switched the oil pump and the oil pump shaft, installed the motor again and it made the same noise.
Since the problem was discovered, all the diagnosis that we did, all the parts switched out were run by Paul first. My fear is that there is something majorly wrong with the motor. I know I'm very inexperienced with cars but I just feel that something is really wrong with this motor. I just think something was missed after it blew up on the dyno. When I sent the motor back and Paul found the bad distributor bushing he said and posted that the motor looked "great" after he disassembled it. He posted pictures of the bearings as well. Next thing I know, I'm told that Paul missed all the damage to the piston rings, bearings, crankshaft and the block needed a light honing. I think as easily as he missed "The recent damage", he could have missed the real problem. The oil pickup tube was not welded. That's something else that was "missed". From I'm told, that's a pretty standard thing to do and most guys do that because of the potential of that happening to these Pontiac motors.
I think it's the same noise. It may sound a little different because one video was in a garage and the other one was outside but in person...it's the same. My buddy who has been building Pontiac motors for over 37 years agrees. He's the guy that's been working on my car!

Originally I was told that it would be too difficult to hear that noise in the dyno room but now....I'm told the motor was not making any noise on the dyno. This last time on the dyno was allegedly the 4th time it was run on the dyno!
