Axle Ratios

Here's my problem.
My truck(below) needs a new rear end.
It has 31 spline axles(the truck is up on blocks with no tranny and the axles are pulled)
I have both of these gears(3.10 or 3.5:1) so thats not the problem. the problem is I can't decide which one to use.
I want decent mileage and acceleration.
The truck has an aftermarket ford 4sp without the granny first gear.

Which one would you choose?

Axle Ratios

Cody, I'd go with the 3.5 axle ratio. I think that's a pretty good compromise for performance and economy on trucks with stock 15" or 16" wheels and tires. I don't know how tall your A-R wheels and tires are, but that would make a difference in selection of axle ratio.

[updated:LAST EDITED ON 29-Dec-02 AT 12:42 PM (EST)]Oh they are 15x10s i think, but we have to change tire size because of tire rub with the drop so they are gonna be something like 235s or probably shorter

Axle Ratios

I have 3.50 to 1's in my 1980 with 31x10.50x15in tires on it. It seems to be a good all-around gear for highway and pulling. I do occasionally have to put it in 4wd low when I am pulling another vehicle out, or doing some manuevering in the field on a steep hill(it has a c6 auto).
