That's a badass build...that must be one very depressed/suicidal dyno. Your actual rwhp should be about 100hp higher than that.

Contact Katech. They likely have the dunk from when the motor was built.

Normal dynojet will show about 560-570 for your build. Dynojets for stock LS7's can vary 420-475 at the wheels with 440 "normal".

My CPR build with the K501,MSD,NW102 and WCCH heads on 91 was 602 on a dyno that stock was 469. What I know is I gained 133 rwhp peak to peak and 170 rwhp at 7000 rpm.

No reason to be disappointed with your Katech build.

run it at the track, that's what matters. It will be obvious if it traps like like a 475 rwhp or not.
