OK, now I see the recommendation. From July 2007. As you can see from the explanation and the dyno sheet, this is a nitrous-biased cam (200-300 shot). The curve of the 100 shot dyno show that your valve events are consistent with what will pull into the 7200 rpm range, but the pull is not as clean NA. This leads me to believe you're getting an intake restriction. Could be the intake elbow. Not many people have performed well with them on single planes unless they're running forced induction or nitrous. It would be interesting to see how you'd run with an Accufab top-mount throttle body.

It won't hurt power so much, but it will bias the engine further to making peak power at a higher rpm.

There have been a few road blocks. After the dyno session the cam has been straightened out, he has a different added a 4150 style TB, fixed some electrical issues and fixed some of the problems with the tuning (or tuner). Transmission have been the real issue from getting to the track, but that is also coming together. New stall will be in Tuesday, and might have some motor track times next weekend if the weather is good and maybe some 150 shot runs also if everything looks to be in order.
If nothing bad happens there then some 300 shot runs will soon follow.

The only real dyno numbers he has are above. After the TB swap it went back to C.A.M. and it was running rich, Jeff proceeded to lean it out and it was all down hill from there. All it would ever do was just surge on the dyno. He loaded about 3 different tunes with no noticeable difference. The the tranny started acting up (probably from the excessive heat off of the super lean engine) and puked fluid out the overflow. That was it for that day.
After getting HPtuners and comparing some VE tables from similar engines and some timing adjustments it cranks and runs better than ever. Once the transmission is back in we will get some more logs and better the tune. Then we will get some track times.

The converter will be in Monday and I have the trans waiting to go in it. Joncr96z and I have been playing with my 07 silverado to pass the time.
