Thanks for the comments. I just don't want anybody to think the R/T is not going to perform. It's just not true. I am fairly confident we will see a quarter mile time in the 13.3 to 13.5 range around 103 - 104mph especially with a stick. Also fuel economy was mentioned in another post. Believe it or not the new 5.7 should do better than expected. The compression ratio was raised to 10.5 to 1 and it has variable cam timing. These things contribute to better efficiency for sure. I think on a pure highway run, if you can keep it at 60-65mph(I know that's hard to do in some areas) you should see better than the 23mpg sticker on the stick R/T. I just don't feel that is bad mileage for all you are getting. The other cool thing is with the bolt on mods your mileage should INCREASE a bit also. With some of the easier bolt on's you will be able to match the 6.1's output. Headers and exhaust, CAI and a tune will equal or exceed the 6.1. This will be about 2K worth to do it(assuming you are doing the labor). Factor that into the purchase price and you can see where you stand. Lear4406, I agree in that the NA engine is a lot less complex and costly in the end(most of the time) if it can make the output itself. The 4.6 Ford is a good engine but it is limited by it's displacement more than anything else in NA form. But no matter, I love both the cars for what they are and can't wait until I can order my new Challenger. I do feel Chrysler hit the spot with this one.
