Range Rover Mark II / P38
So after installing 4.10's and True Tracs, along with my 32" tires, my engine runs at a steady 2600rpm (or at least between 2500 and 2700) while on the highway. At 60mph it's just about bang on 2600rpm. I don't usually let it go above that, as I'm ok with keeping myself to 60 - 65mph limit now...
