I have a 2012 Gasser, and I'm about to take a trip that will put me on the Rockies more than once. I was looking up the ratings to find the 'sweet spot' RPM's, and this is what Ford lists:
Horsepower 385 @ 5500 rpm (6.2L V8 under 10K GVWR); 316 @ 4179 rpm (6.2L V8 over 10K GVWR)
Torque 405 @ 4500 rpm (6.2L V8 under 10K GVWR; 397 @ 4179 rpm (6.2L V8 over 10K GVWR)
So my question is: why is the 10K GVWR rated so differently? What does this mean? I don't even quite get why there is a 10K rating vs. 9.9K rating in the first place.
Anyone?
If you have that right, it is strange that the under 10K has a higher HP and torque than the over 10K. It is stating lower RPMs, so likely the same tune on the engine, just weird.
