I saw a guy tonight at the Wheelin' in the country park in TN that had 46 inch boggers on his XJ. Of course it looked like a frankstein jigsaw puzzle, but this guy still had the 4 liter, (not sure what gearing) and was running 65 and 70 MPH with absolutely no problem. I couldn't tell exactly how much lift he had although he had a complete sub-frame under it and some pencil rigged metal work. This guy had to stand on a stump to get in the thing, any idea how he built this monster and held it together?, not to mention what gearing this guy must be running?
