Include any of the following information possible:
Axles and Gear ratios
Tire Size
and of Course MPG

If you are looking for MPGs i would go with a diesel. 4BT swaps are getting more common.

Would like to do a drivetrain swap in the future and always like to see what others have done before making any final decisions on what parts I want to use.
