As for gears I think I got stuck with 3.55 but 3.92 may be installed since 1st owner literally chose every option possible. I just haven’t checked yet. > > 390/406 is power specs, 2013 is 395/407 iirc. Im not brand loyal when it comes to trucks so I drove everything when searching. 5.3 is gutless aswell as 5.4. Then I was on a silverado ss kick for awhile till I drove one… 6.0 little better than 5.3 and ford 5.4 but still worthless. Sounds like your mileage is right around mine. You may have the 3.92’s…world of differnce to the 3.55’s I have driven both. I am brand loyal only to dodge/chevy i just fucking hate ford trucks and refuse to ever buy a nissan/toyota pickup. I am suprised you feel that the 5.3’s are nutless though! I had two of them and thought they were great! My hemi is def faster and shows better torque but i was never disappointed in either my 2004 or 2008 5.3… I drove an SS silverado hated it thought it was dog slow and owned an SS trailblazer. The 6.0 is just overrated when put in that platform. --- _[View the full topic](https://forums.speedlife.net/t/modding-4x4-trucks/267601)._
