To tell you guys the truth... I'm leaning towards the R/T. I love the SRT-8, but I'm a modifier and there will be lots of trick stuff for the 5.7. Not saying there won't be for the 6.1, just stands to reason that there are more 5.7s and if I'm a tuner, I'd go with the odds. And I have $10,000 dollars more to spend on it. You get so many goodies with the SRT-8 and I know me. I'd more than likely stop with an intake and exhaust. With the R/T I'd put headers on it and a super charger as soon as the warranty runs out. I'm on the fence and its different each day. But I'm going to take the plunge soon and when I do it will be with alot of thought I think they are both great packages and you have to make that choice that works for you. As far as SE, again great looks with better gas mileage for those who like to cruise and be seen Can't go wrong when you choose a Challenger.
