what kind of times did both cars run?? what was the mph of both cars?
most challenger guys i know that run autos run with the traction control on. and even then its tricky to launch them. the guys that have figured them out can get a basically stock r/t into the real low 13's while others are running high 13's to mid 14's.
ok so you are at about half way to the price of a new camaro. and so far all you did was beat it in the quarter mile. now go make it not only beat it in the quarter mile. make it beat it in comfort, luxury,cornering,stopping and mpg. then let me know how much cheaper the dart was to build. the camaro like the new challenger and mustang are built to be all around good performers not just a straight line piece.
