I figured to step up to a modern day mopar muscle car and purchased a 2010 challenger ,but still have my dart sport that I run occasionally totally stock and slow. I had upgraded about two years ago to a 8/34 rear diff with a rebuilt 742 3.55 rear. did it as a duel purpose car street/ strip. Anyhow after I did some research on the challenger, not for the racing, my fault, but thought as I get older, heated seats a/c , cruise ect would be better that the wife and I riding around without all the comforts of an old car. So after the research it appears as though I feel like I made a mistake. The challenger looks as though axles, driveshaft, snd running DOT slicks, need to be replaced, all not even cheap. I figure to upgrade the dart to similar HP vs. the challenger, now not so sure. This is not a SRT ,only an R/T5.7, any thoughts ?
