Nothing. He is absolutely 100% correct.
Please explain, in detail and with links to sources, EXACTLY how 300HP from a Ford V10 spinning 4500RPM is different from a 300HP C10 Cat at 1700RPM, 300HP from a Cummins ISB at 2400RPM, or 300HP from a turbocharged Honda at 8500RPM. If each engine is moving equal weight and geared appropriately, they will perform exactly the same climbing hills. It is basic physics!
Note: been there and done that at work. We had two tractors, both with 275HP...one got 275HP with about 850lb/ft from a big Cummins (I think an ISM), one got it with maybe 600lb/ft from a Cat C7. With the same weight, they climbed hills at THE EXACT SAME SPEED. The C7 just had to spin higher, and was geared accordingly. (Power peak was 2300 versus, IIRC, 1800.)
