Again, interesting spreadsheet! My butt dyno denies the low torque (haha), but the little bit of highway I have done is confirming what I see over 3k. My truck is pulling hills in 5th around 3k that definitely required a downshift before.
I completely agree with no low end with the 261 cam. On my way from Utah to Montana and home to Washington any time the RPM'do went below 3k I was down shifting.
