I have heard a rumor that Dodge is working on a variable cam timing and MDS for the 2nd generation 5.7 Hemi. It will also produce more hp (possibly 370 hp), more torque, and better fuel economy. This engine will, supposedly, be in the R/T for 2009 The 6.1 will be in the SRT.

If this is correct, the 6.4 Hemi may not surface until 2010,as a SRT HO option, when it will compete with the Camaro. [:@]
