What kind of RPM's are you 4.10 guys running at 70-80 mph? How bad did the 4.10's affect your fuel economy?

sweeet. I'm seriously thinking about them because I needs a new pinion bearing so I may as well throw some gears in at the same time.

I am at about 2400 rpms at 70 in OD. 2400 RPMs is a little much for me, so it has actually slowed down my driving on the hwy. I cruise at like 60 mph most of the time...or with the flow of traffic. And at 60 mph, I see 2000-2100 RPMs. Much more livable. But the 4.10s are pretty fantastic!
