C6 Z06 Makes an Extra 100RWHP Easy
Here is a VERY clean 2008 C6 Z06 we just finished installing a custom grind camshaft in! She picked up an easy 100 RWHP! It is amazing how much power you can pick up in these with such little modification!

Please show Dyno chart of both oem cam and your cam, but to full 7K pulls for both; since the LS7 pulls all the way to 7k before the rev limiter kicks in.
The problem on the LS7 in the C6 has always been that motor runs out of air and starts chocking for more air about 6.3K since there is not the needed room under the hood for the needed size intake manifold to begin with.
Hence you can add more lift and change duration on the cam to pull more air in below the 6.3 mark to make more power down lower, but all this does is cause the motor to start starving for air before the 6.3K mark isntead. In the video dyno graph you show, the motor is already going flat/starving for air around the 5.8K mark/HP going flat from there with the new cam instead.
Simply put, stock LS7 problem is not cam, but being able to breath above 6.3K, and why with even a supercharger on the car only putting out 6lbs of boost to just allow it to breath correctly all the way to 7k, the LS7 will put out 650HP on stock cam and exhaust with a ruler straight line of HP increase from idle to 7k instead..
