Well Dskippy, I'm one who would like to see this happen, the problem is it won't produce 300 hp with the output of the 5.7L nor the output of the 6.1L without further modifications. I would say a 4.2L Hemi on the basis that would be about the displacement of a V6 made directly from the 5.7L and the output would be around 275-280hp but the tq would be about 300ft-lbs and it could benefit from the MDS and probably get better fuel economy as well as maybe cost less than the 3.5L since this engine apparently isn't that expensive to build.
