Don't expect a 5.7L to be offered in the SE is my advice, even on cars that have only one real version beyond "special editions" like the Viper always have to have the exclusive badging of SRT. A V8 is not going to be offered in a SE trim. The truth of the matter is it appears that the Challenger R/T, will not be as luxury obsessed as other R/T packages, so that might work just as well for you.
