It will pull it, you are correct. The question is how well? If you get the RPM's down too low on the highway, the mileage will tank because he'll have his foot in it all the time (I know thru past experience on this one).

If it was me, I'd look into a happy medium. 3.42 gears would be a much better choice. With average sized tires, he'll be around 2500 @ 70 MPH and still have enough low end to start out on a hill without obliterating the clutch in the process.
