The E-Body Mopars are going for more money because of the 1) Over all look. 2) Not many made. 3) the reputation they have in the minds of the buyers. I think they have an appeal that allows the buyer to feel much like a Harley rider. The car looks mean and has been used that way in movies and shows it has co-starred in. I've seen them pull R/T Challengers out of the junk yard with no engine or trans and sell it for 1000,s. More parts are now available and the car can be made to drive like a 2008 Model.
Any modern 5.7,6.1 and 6.4 can be droped in with just a K-member change.
