How fast are you landruiser 2F owners running on the highway?
I keep the rpm's under 2500 for the most part, and I figure 2300 or 2400 is about 100kmh with my 35's and 4.11's.
When I rebuilt the motor that huge ,heavy crank does not look like it would enjoy sustained high rpm use, and since I spent over 2 grand rebuilding it I want to preserve it as long as possible.
So......how fast do the rest of you go?
Am I being overly cautious? Or will the six tolerate higher rpm?
I know the motor makes max torque at 1800rpm (240 ft/lb) and max power at 3600 (140hp), so the book says it can rev much higher than I push it.

90-100K with 245/75R16's (31's?) and I'm all revved out. I've gone a little faster but it doesn't seem to want to do it willingly or for a long time, unless I'm going down hill :D. I will eventually get some 33's for it but until then, so much for driving across the country in it.

Dumb question time, how do convert the metric tire sizes to standard? I assume a 245 is a 31 and a 265 is a 33 and so on.

devide 245(millimeters) by 25 or ruffly that.thats how many inches wide the tire tread is.in your case close to 10 inches.the 75 is the aspect raito(sidewall %) so 75% of 10 inches,7.5 inches X 2(since from top to bottem of the wheel includes two sidewalls)=15 inches
add the 15 inches to your rim size,16 inches=31
so your tire is a 31-10-16 or close to that.

I guess these machines were never intended for cross country travel on interstates. But I do run mine down to the U.S every year.
On the bright side, I get to put on larger tires to improve my highway rpm, not the other way around as it seems most modern trucks do.
