500" Dyno

I'm in the final process of finishing my new motor and thought I would throw it out there to see who can get the closest guess on hp and tq. It is going on the engine Dyno Saturday January 26. Engine specs are
77' 440 block
Bore - 4.375"
Stroke - K1 4.15" crank 2.2" journals
Rods - K1 6.76" ARP 2000 bolts
Pistons - Ross flat tops .990" pin
Pistons are .007" in the hole with .047" quench
11/1 compression
2275 gram bobweight
Hughes main girdle with stock caps
Milodon external oiling

Hughes solid flat cam and light weight lifters
Intake .651" lift 268 duration at .050"
Exhaust .661" lift 272 duration at .050"
108 centerline degreed at 105
Harland sharp 1.6 rockers

Heads are Indy EZ-1 set up and ported by Modern Cylinder Head

Intake will get experimented with on the Dyno. Starting out with an Indy tunnel ram and 2 750hp carbs. Will also try Indy single plane with a 950hp and a 1000hp. I will use whatever has the best curve.
Im hoping this thing will be all done by 6,200-6,500 rpm. This will be run on pump 93 octane. If I am missing any info let me know. So lets see who has the closest hp and tq guess and at what rpm.
