At 17 years of age my first Challenger wasn't the best-'73 340 auto, but I could take about any street driven big block out there because of my familiarity with the car after a few years. So many people make the mistake of thinking that cubic inches equals unbeatable performance, but I made believers out of a few big block muscle car owners with that little 340. Some even became converts. Like I said I will own the car till I no longer drive so appreciation is not a factor as it will not be a low mileage vehicle. I owned my '73 for 17 years and beat the crap out of it until body cancer and growing kids made me have to part with it. There just wasn't the money to fix it and I couldn't stand to see it sit and rot any longer. The day I sold it I took it out with 117,000 miles on it and as a final goodbye drove her to 120 mph. Pretty sappy huh? She was my first love though and I have countless memories of that car and good times driving her. I don't think 6.1 or 5.7 will make that much of a difference to me as I'm an old man now and I just don't drive that fast anymore. You guys do what you think is right for you and you'll build some of the memories I keep.....I'll bet that Scott county sheriff is still pissed that he couldn't catch that old DODGE.
