I like the 4.10 I installed in my 3/4-ton but I still am comfortable with only 45-50 MPH. Driving the back roads to Portland might be OK and fun but I'd be scared with I-5.

I occasionally drive I-90 in MT at 50 MPH (speed limit 80, actual >>80) but I hang a blaze orange triangle in the back, turn on the flashers and spend most my time looking in the rear view mirror ready to dive to the right. What a guy doesn't do to get to his fishing spot.
