There is so much more to this than most guys realize.
I clearly work my engine harder than most.
The Aussie guys clearly outwork me without hardly trying.

I never pull to 1400. I always try and shift before 1500 or above...16-1850 is my preferred range when pulling bigger hills.
I run loaded 55-57 mph at 1620-1670 rpm in 17th gear.
I run empty ~60ish at 1500 in 18th.
When I did my inframe I had no liner fretting. It was before I found this sight, so I didn't know to cut the counterbores and raise my liners to 0.015", so they are still set at factory 0.010" and I know I'm living on borrowed time...
