I second what everbody else has said. Not a good combination for sure. However, tire size might also come into play with your calculations.
2000 rpm is a good place to be at 60 mph for a 235 6 cylinder motor. 3.08 gears with 26 inch tires (205/70r15)and a .86 od put you pretty close to 2000 rpm at 60mph. Most of us run taller tires on our trucks.
I prefer lower gears for better acceleration and grunt. I currently have 3.70 gears with a .73 od in my truck, but will be changing the gears to a 4.33:1 ratio to get a little more grunt. The 3.7 gears worked well with 28 inch tires (275/60R15) but do not work well with my current 31X10.5R15 tires.
There are a lot of variables to consider when building these trucks including but not limited to the following
Size of truck
Size of tires
Rear end
Gear availibility
Motor
Transmission
How it will be used... work truck? daily driver?
Personal preference
budget
etc.
What might be "gold" to one may be "crap" to another.
