FE Technical Forum / Dissapointing day at the dyno

Well the good news is it didn't blow up. The bad news the numbers were very disappointing 415hp and 465tq. I was embarrassed needless to say. The owner of the shop has a 390 Fairlane. and it did 50 more hp with 60 cu.in less and basically the same set up. Af was 13:1 he said it was lean, I thought anything under 14:1 was OK. I thought I knew what I was doing but its clear that I don't. I was expecting at least 500 hp. The car sounds mean just but it makes a little more hp than my Suburban. Any suggestions would be appreciated. I was planning on going to Maryland at the end of the month but now I have my doubts.
So here's the specs
428 block .040 over Eagle 4.25 stroke crank, Scat rods, Cp 10.5:1 pistons, Barrys cnc ported Ed heads intake 310cfm exhaust 178cfm I think. custom Comp cam solid flat tappet very simialar to a 294, ported Streetmaster, Msd ignition, Hooker 1 3/4, flowmaster 50s 2 1/2 out the back, Holley Hp 850, fidenza aluminum flywheel,TKO-600, 389 rear. I think that covers it.
Suggestions welcome somewhere there is 100 plus hp hiding
