I've got 22mpg in my truck with 4.10's and 30.5" tires. I get better mileage driving around in 3rd with the RPM's up around 2K, as opposed to lugging OD/Lockup up hills at around 1,300rpm for example. I changed my shift patterns to help me out there.
I'd look into 4.56's if I didn't have a front diff to worry about. I love short gearing.

With Chingys setup he will rape me till about 70, then ill come back and pass him. So what do you finish your 1/4 at? I know its more than 70 mph
Its not like if you add 410s you get more pull and more top end, something has to give. Take off is great, but I dont like to rip *** off the line then get my *** handed to me at the end
Also if you look at the fastest truck list there arnt many running 410s. Most 373s if I remember correctly.

With DR's or slicks, sure it takes off out of the hole like a bat outa hell, but to me thats just not practical. I like driving on the street and my races mostly happen on street tires on the street.
I got a posi and was going to do 390 gears knowing 410 was higher than I wanted to go but my plans changed. Now im gettin a 3500 stall to make up for my low end not being there, and see how the 342 gears like a big stall. If I still dont have the low end I want, I MIGHT go to 373s, never 410s

hey, when you try that let me know how it does, i was planning in doing that maybe in a few months??? i already have the 342s but i was thinking about a 2500 stall???

With that same thinking, wouldnt you say that if you had 342s you might not reach your power peak as fast (solved with stall converter), but you will stay in your power peak alot LONGER, right?
