Will I regret change to 3.55s from 2.76s

What is the fastest speed you want to drive long range on the freeway?

Did you change valve springs?

A gear change will really make it a different car.

How much do you drive it? Do you want to make long trips?

Here is my story.....
I pulled the 4.10 from my dulley ram to install a 3.56.
Picked up 2 MPG around town with no load at less that 50 MPH.
But towing my trailer at 6K lbs it became a DOG.
If you look at Torque RPM Chart I moved the engine into a shitty point on the curve.
So I put the 4.10 back in.

Think about that.
I'm never on a road with a speed limit higher than 55 and never drive over 60-65. I did not change the valve springs yet but I have Comp 901-16's new in the box. I normally drive it 1500-2500 miles a year in nice weather and don't have any intentions of any long trips. Obviously, the hotter than stock cam doesn't make much sense if I leave the 2.76s. While answering you guys questions, the 3.55's seem to be becoming more of a no-brainer.
