I don't like your cam. You could have used the 284/.484 106 LSA MoPar cam and had the same vacuum at idle and picked up power everywhere.
RustyRatRod just posted three great links in the I don't understand cams thread. I suggest you read those threads. They have every good info.
Also, can you post the BSFC, BSAC and BMEP numbers. Can't tell much more with just the numbers you posted.
BTW, if you blow a head gasket on the dyno by pulling the engine down, the dyno operator has issues. I'm not a big fan of pulling them down farther than actual bottom of engine RPM range, but these guys are correct. He should have pulled it down to 2500.
