Stimpy29, you left out an important part of the equation. How tall are your
tires? Guessing they are around 28" on up go with the 3.55. With all that
torque sounds like you are going to have one mean tire shredding machine!
P.S. A 28" tire w/3.55 = approx. 2530 rpm @60, 2740 rpm @ 65mph and
2950rpm @ 70mph. Hope this helps.
