Should I change gear ratio?

After completing my 4.3 to 6.0 swap, I got to looking at my rearend gears. I found out they were 3.08 gears. Probably not the best for what I'm trying to do. I heard they are a highway gear. It takes off pretty well, but I think it could do much better with some different gears. I have the stock 5 speed in it, and don't want to get too low of a gearing. It's a daily driver. From what I have been reading, 3.73 or 4.10 is a choice set of gears, but they are all with automatic trans. Don't know if it would be different with manual. Any suggestions?

nothing different go for it

:beerchug: i agree

yea man i went from 3:23s to a 4:10 and it was like bolting on a blower you gotta drive it around for a few days and let the gears heat up and seat then let that bitch rip, and at 70mph your running abour 2100 rpms, my truck is pretty much stock for engine mods and i run 14.9 to 15.2 depending on weather and stuff so yea get some gears dude:burnrub:

Do it. you will definately feel the difference. :twocents:

You guys are running 2100 rpms at 70 mph? I'm running just shy of 2000 rpms at 70 mph. Maybe my transmission is lower geared.

that OR a bigger over all diameter wheel and tire combo

my over all tire is 31.25 inches,and if your transmission is lower geared then you'll run at a higher rpm, i didnt really notice much on the change of the rpm's as much as i could feel it in the torque once you hit 75-80 it raps quick and your gonna top out at about 122. but who cares you'll be through the 1/4 by then

Should top out well over 150+ but you wont makeit there by the 1/4 anyway unless you have 1000whp

Im just goin off of what my gears top out at and its the same with txakitekt, he also has 4:10s. mine is programmed to 130 but i never get there.
