I just purchase an xj that has already had some modifications done to it. It currently is running 33/12.50's. I was wondering if there was a way to check its gear ratio by the RPM vs speed. The speedo has not been changed, but it shows in 3rd at 2500 running 55mph (which is probably closer to 58-60 with the tires). Anyone want to throw out a guess of what the gear ratio might be? Thanks.
