dude your only 16? Trust me the 5.7 will be plenty of power I bought mine when I was 18 and It didn't dissapoint. Matter of fact im looking at getting the re-vamped 5.7 unless the 6.1 is gonna be standard R/T equipment. I don't have 40k to spend on a car, even over 5 years and im not retiring soon. Im going all black for sure. The 6.1 is whack unless it totally replaces the 5.7 just my opinion waste of money. The 6.4 will be very exciting to see though. But im definatly waiting till mid-year to see what's really gonna happen with this line-up.
