Final numbers from first session:

7300 567.6 788.9
7400 565.8 797.2
7500 559.8 794.8
7600 557.3 806.5

8100 538.8 831.0
8200 537.0 838.3
8300 535.8 846.7
8400 534.2 854.3
8500 525.4 850.3
8600 513.6 841.0
Specs:
-4.125" C5R block
-Callies 4.00" lightweight crank
-Manley billet steel rods
-Custom Diamond pistons 16.1 CR
-Dailey dry sump pump and pan
-Jesel belt drive and .937" lifters
-Custom FMS cam 28x\30x .921"\.880" 114 LSA
-Meaux racing ported C5R heads 4xx intake CFM
-Manley tit valves,Nextek 1.647" springs and tit retainers
-Jesel 1.85 Mohawk rockers
-Beck intake w\105mm T\B and 96lb injectors
-Custom FMS 2.125"-2.25" stepped stainless headers
VIDEO
This was all done on break in oil,no synthetic oil wihcih is good for 15-20 HP and Meaux's dyno is a conservative dyno. Figure once we get done on his we will travel to a local dyno which is 45-50HP higher

He just mislabeled the headers, that is 850hp. If he could make 850ft lbs at 8500 na he would be a god.(850ftlbs@8500=1300+hp)
Great job Allen and crew!!
Kurt
PS: what controller?
