What HP would this configuration create?
What kind of HP can I hope for with this configuration?
BB 427
Hydraulic roller Crane cam grind number: HR-288-2S-12 IG
Cam Timing: @.050
Lift: Opens Closes Max Lift Duration
Intake 6.0 BTDC 40.0 ABDC 107 226 °
Exhaust 54.0 BBDC 0.0 ATDC 117 234 °
Valve lift: .587 intake, .610 exhaust
Crane gold roller rockers
Standard TRW forged piston
AFR 305CC heads with 119cc combustion chamber
(Should be around 10:1 compression)
Dual plane LS6 intake
Hooker headers and sidepipes

I have almost the exact same combo. Looks like DD is right on the money...or Travis is just really good. 
I don't have the chart in front of me, but mine made 450rwhp/465rwtq. Peak HP was @ 5600rpm (and only dropped 20rwhp to 6400rpm). Peak TQ was at 3800rpm.
I don't know what this is at the flywheel (DD #s), but I figure ~530hp/545tq considering 15% driveline loss.
My combo:
AFR 305 heads...~9.5:1 CR on my motor (454)
Comp Cams hyd. roller cam (232/232, .588 lift in/ex, 112 LSA)
1.6 Magnum roller rockers
Edelbrock RPM Air-gap intake (required L88 hood)
Hooker side-mount headers w/ JCL inserts
The thing makes an incredible amount of TQ at low, mid-range rpm but still pulls plenty high in the rev range for a hyd. roller motor...so much that I had to take some gearing out of the rear (I'm running 3.08s now). Of course, I have a Richmond 5-speed, so I have a nice low 1st gear.
I had an LS6 dual-plane low-rise intake that I decided to pull off. I honestly figure it cost me ~15-20rwhp. To some that's not worth it, I know.
