So yes, the 4.3 is weak, makes little low-end power, and must be held in higher RPM to extract any of that V8 equivalent power you speak of.

Yes I have. Overlap the charts. I’m not talking about peak numbers.
2014 ecotec3 4.3L 100,000 miles 19.1 mpg lifetime average crew 4x4 with current gas price 2.65vs 2.25 you would need to avg 22.5mpg in the 6.2 to break even. Is that happening?
