Casey, The easiest way to increase your speed and drop your RPMs is to install an overdrive unit between the bellhousing and transmission. Look up a company called Advance Adapters. They have a Ranger Torque Splitter that is only 7" long, 27% drop in RPMs, bolts to the bellhousing and your transmission bolts to it. Extremely easy and your speedometer remains unaffected because it mounts before the transmission. You will just have to move your hole in the floor 7" back for the transmission shifter. The unit that they sell does need to be shifted manually. If you're interested, I have one for sale that has an electric shifter that shifts just like a 2 speed rear end with the shift switch on the transmission shifter. Asking $800. DaveV
