Default Re: Gear ratio

I think Ford did a good job with stock rear ratio, if you start doing modifications it has to match--- put in a cam that raises the torque peak and then change the rear to make the engine run below torque and you can end up with poor fuel economy and low power, functionality lugging the engine
Years ago the rear went bad in parents motor home, I had a cube van and the rear was borrowed from it, the original rear in the motor home was 4:11, the cube van has 4:56, with that rear the motor home got 1 more mpg on a trip to Florida--- 10% more mpg--and yes, the cube can sometimes sound like it needs another gear
