Engines with lack bottom end power?

It sounds to me like you are having a gearing issue. You stated that you have 2.xx gearing.
I know my car has a gearing issue, this ain't about my car directly just using as an example,

The take away my engine makes 380 lbs-ft at 2500 rpm a stock cammed magnum makes 385 lbs-ft at 2500 rpm which is way more then enough torque more than any stock /6-360 all those engine will work fine with 2.xx and stock stall why won't mine? I'm obviously making more than enough power down low.
