My buddy who owns a '10 Camaro SS stopped by to look at the 392. He loves the car and the power it has, he asked me why does some Challengers have both RT and 392 Hemi on the same car? I told him that is for all the Camaro and Mustang owners out there that wants to jump out on these poor RT 5.7L. He couldn't stop laughing as I told him what I think Dodge really did. At first I didn't get it but in the process of making a decision while thinking about getting my car I've learned a lot from you guys and gals here.
