Engines with lack bottom end power?

I think the assumption you are making about the 300 and 380 magnum crate engines having the same torque curve is wrong.

Big difference in the two cams in these engines, so likely a bigger spread in the low end torque curve than you are thinking.

i looked at the dyno number a bunch of times, the 300hp been dyno'd a few times over years, Richard Holdener re dyno not to long ago as well as a scrapyard 5.9l and the 380hp been also dyno'd a few times.
