Keep us posted on what you find out on that noise. Best of luck!
Correct the engine was built in Michigan and I'm in Florida.

I have asked Troy about it and he had one of 2 options, either hydraulic lifter of the chain tensions for the oil pump.

I got 2 cans of Liqui Moly Hydraulic Lifter Additive and the sound at idle is not there but still under acceleration between 2-3K when off throttle it's there.

BTW when I changed the oil last week there was 0 residue or any metallic particle on either of the magnetic drain plugs...

So I hadn't had a chance to get the video of the car revving until this afternoon.
