New Build Complete; Disappointing Dyno Numbers...BUT

With the intent in mind to increase the durability, drive ability and overall street, track performance I changed up my original combo from a LPE 660hp built car to the following.
Hutter built short block with Mahle forged pistons with 1mm,1mm,1.5 rings (Rebuilt Due to COMP TRUNION FAILURE) with only 6400 miles on it.
Katech Blue oil pump with modified pan.
Advanced Induction 280cc heads
Stock GM rockers
Tony Mamo spec'd Mild 240/252 cam
Johnson short travel lifters with pressure feed oiling
Manton pushrods custom lengths
Tony Mamo MSD ported and shaved manifold
Halltech 103
AR headers and Corsa exhaust
RPM level IV transmission
RPM rear end with 3.73 gears.

The car runs ALOT stronger vs the LPE 660hp package which had the larger 243/259 .700" cam. The driveability is great very smooth above 1600 rpms NO surging. Have only put 200 easy miles on it so far but the seat of the pants feel is unreal. BUT the dyno numbers are not doing this package justice. BUT again, when I picked the car up from Hutter's dyno shop his first question was what is your setup exactly?? Because that is the highest Dyno numbers they have seen from a street driven Zo6 with LS7. He also said the next higher car Dyno'd at 582hp and runs 9's. He said to compare with Dynojet numbers I would fall between 620-630 HP. SO, with that info and how the car drives I am very happy with the setup. SHOUT OUT TO TONY MAMO, PHIL at ADVANCED INDUCTION AND BRIAN TOOLEY FOR HELPING ME ALONG THE WAY!!
