chassis dyno results

I took my last 500" motor build to the chassis dyno today. I mainly wanted to see the fuel curve. I have been messing around with my fuel curve trying to tune it with my LM-1. My fuel curve looks good, the results are:
Max HP 590
Max torque 558.31
That was without the air cleaner. With the air cleaner:
584.83
568.28
I don't know why it lost 10 ft lbs of torque going without the air cleaner.
Recap of the motor build:

Indy SR 295 CNC

272/276 @ .050" .610"
Mopar 337 Manifold with 1000 CFM 4150

On the engine dyno it made 708 hp
