Magnum 300 crate engine - how should it go when tuned up right?

Thats a dyno comparison 300 hp create vs comp cam eddy airgap and heads. If i remember right a comp 275 hydraulic roller cam.

There no way that engine can be as dead as you say especially with 4.10, something got to be wrong. I got a 380hp create engine and its pretty soft under 2000 rpm and i only have 2.94 gears for now. And it still goes pretty good.
