414 Dyno results: Missed combo?

I like how that HP line goes up and up and then just simply hangs in there for a long duration. Killer torque line where she counts!

Why?☺
@RAMM have you calculated intake port size/length for this camshaft?
In my car,i think this is a boring engine☺ it will fall over before 5000, not any fun to accelrate when you cant rev it out. Sure its cool when you stump it, it light up the tires instantly.
