If you are running 5.29's and 35's on a fresh rebuild, and having power problems, then something is wrong. I am running the same on a 250k mile engine (original rings, with replaced HG and rod bearings, no smoke, but uses 1 qt of oil per tank of gas), and can run 70 at half throttle. I would take another look at the engine - timing, plugs, sensors, carb... something is killing your power. The 22r should be making enough power to push you.
i'm runnin 37's 5:29s and a 20r/22r hybrid. i can cruise down the highway at 70 pretty easily. my buddy has a 99 cherokee with the 4.0L and 33's, and i can keep up with him.
