Engine Mechanical / Electrical / Ford 460 power question

Hello.. i got an issue with my boat.
I have a Glastron CVX20 with a Berkeley JE12 pump with A aluminium impeller. Place diverter and the "sports" loader i think.
Pump is recently rebuilt and the impeller looked like new.
Stock this boat comes with Ford 460 rated at 320 Hp, turning the A impeller at 4600 rpm.
Now i have a new built motor, a Ford 466, it did 485 at 5150 rpm in the dyno.
I have been kind to it in the beginning almost just have run it on the primary jets...
So after some days i thought i should open it up and see how it would run at full speed.
At first i notice that the motor stalls for a split second when i open the secondaries, then run as it should..
But it's only turning the A impeller at 4500 rpm.... so i got the same speed as with a stock motor..
What do the jet people think, shouldn't it be going faster?
