I first want to say that I love this site! I have a 1964 Jeep CJ5 with the stock gears ( 5.38 ). My top speed is about 30-35 MPH. I was wondering if anyone that with this setup, has changed the gears. I would like to get a better top end speed so I can at least drive 45 MPH comfortably; however I do not want to loose all power. I routinely take my jeep off road, and want to make sure that I still have sufficient power. I was thinking of 3.54; however I wanted to see if anyone had already done this. I have a completely rebuilt engine (less than 100 miles), a Weber 2 barrel carburetor, and a flame thrower high performance coil. I just would like to drive down the street without red lining the engine. Any help would be Great!
