Check allpar on the new phoenix engines. 6 and 4 cylinders. They are really well thought out engines with power and economy in mind. I do not know if they will be built... but they have a lot of R&D in these motors and I would think with the Italian connection they will put out more HP and better fuel mileage than Ford or Chevy. I hope it will be a go. But I am more interested in the 6.4 rumors.
