Couple of Questions

[ponyboy_239]

I have a couple of questions concerning the '10 car. Number one, is Ford gonna release another V8 for the 2010 model year or is the 4.6 all. Number two, I am somewhat uneducated about rear ends and was wondering exactly what the numbers mean and what the difference is between a 3.31, 3.55, and 3.73 rear end. Thanks

The 3.31, 3.55, and 3.73 are rear end gear ratios. Basically the number of times the pinion gear spins compared to the one rotation of the ring gear in the rear axle. A higher ratio will provide better acceleration than a lower gear ratio. Also as far as I've read that the 4.6 is going to be in the GT for 2010 only then being replaced by the 5.0 for the 2011 model year
