    This one is quicky. '82 Silverado w/350, 700R4, and 31" tires. What the best all around ratio, its primarily a city truck with some off roading and lots of snow driving. 4.10, 3.73 or something different?

    Well, dude I am right now running the 350/700 with 3.42's and I have stock 29" tires. And she has plenty of power. SO with just 31's you should have great performance with 3.73's. Then you only use overdrive at 60+. that owuld be the best all- around. Im going to 3.73 or maybe 4.11 with 33's and a 700. But I dont do all the low end crawling that alot of these guys. Just be true to yourself about how your going to use your truck. But you sound like me, part time here, daily driver..... Thats just my thought.

    I miss my Ex, but my aim is getting better!

    3.73 are great for up to 31s but 33s need 4.11s

    I run 33's with 4:10's....if ya run mostly highway, with 31's, then 3:73's are ok.......on the highway, at speed, the difference between the two ratios is about 200rpm...I would opt for the 4:10...if you presently have a 3:42, or (numerically)lower.....you will have to change carriers.....good opportunity to upgrade....JD

    I am running 33's with 3.08's. It drives fine on flat ground, but you slow way down on hills. I also tow with this set up. Don't get me wrong, it sucks! I will be changing axles soon though. I just wanted you know that 33's and 3.08's work, so 3.73's or 4.11's would be great.
