Also, here is a pic of my rpms at 65mph (yes speedo has been corrected) I have 33's and 4.56s

There is a certain range you want your engine at at different speeds, the lower the rpm's doesn't always mean the better, especially if your dumping tons of fuel to it and not going anywhere.

410s or 456 with 33s will make things worse according to this chart putting the 33s on will bring the rpm down http://www.jeep4x4center.com/calculators/index.htm
