Default HP Estimate??

FE experts:

I am running a 428 CJ in my new BDR. Now that I finally have it sorted out in time for winter driving season and it has never been dyno'd, I was wondering if anyone out there can give me an estimate with my engine setup. After perusing several threads, I am guessing I am somewhere around 460 HP and TQ.

Here's the skinny:

Heads: Edelbrock FE Performer RPM Cylinder Heads
Cam: CompCam-hydraulic flat tappett. Duration 230/236 @0.50 , lift .562/.565
Carb: Quick Fuel HR780. 780 cfm w/mechanical secondary
Intake manifold: Edelbrock performer RPM
Pistons: Diamond dished pistons bore 4.185,stroke 3.984,6.49 rod,1.675 cd for 10.17" deck height
Hydraulic Lifters: Comp cams fe high energy hydraulic lifters
Crankshaft: Eagle cast steel crankshaft 3.984 stroke.
Block: 1967 428CJ Ford Service block
Roller Rockers: Pro Comp Aluminum roller rockers
Push Rods: Smith Brothers 4130 chrome moly custom
Connecting rods: 6.490" Eagle "ESP" H Beam Forged
Rings: PBM Power Seal Rings
Rod Bearings: Clevite P-series rod bearings
Compression Ratio: 10:1

Most likely more info than you need, but I wanted to be complete. I plan on getting the car on a dyno this spring/summer to determine the RWHP then add about 15-17% on top of that for an estimate at the crank. Uhtil then just working on completing my documention.

Thanks
