Default Help me figure out my HP....

I ran this thread under a different title without any response, I thought I might give it one more try with a different title..............

My engine is done. I need some help with a rough assesment on what kind of HP I am looking at. I plan on doing a dyno run at some point in the future but right now its not feasable.
If one of you guys is versed in the use of the desktop dyno I would really appreciate you giving me a "run".
Even if you don't have a dyno and are running a similar setup your input would be appreciated.
The engine is a 68' 427 side oiler bored 11 thousandths over standard bore, 428 Scat crankshaft, Eagle connecting rods, flat top Diamond pistons with valve relief, Ferrera stainless valves (I think 2.09 is the inlet sizing, notes not avalilable) Comp Cams Magnum 282S solid lifter cam, 571 lift with 282 duration, Dove roller rocker valve train,
Edelbrock RPM performer FE heads with 76CC chambers, A Blue thunder dual quad intake manifold with a set of Holley 750 four barrels. MSD 6AL ignition system. Along with a the above is a 28lb. steel flywheel. Engine has been balanced and blueprinted.
Our numbers tell us we are running 11:1 compression ratio, with a HP guesstimate of 535+. If anyone checking this thread can give me some insight I would really be thankful.
Opinions have been flowing but I really need a touch of reality in working this out. I realize this would be HP at the flywheel and if any more info from my end is needed please let me know.
Thanks much in advance.

Mark
