if a muscule car is a heavy american car with lots of horse power well than you can say the U.S. still makes some. think of the new mercury(4000+ lbs) , impala ss (around 4000) , lincoln mark VIII (3900lbs).
I own a mark VIII and now it hase the same 4.6 twin cam as the mustang cobra. I have frends that only have $200 super chips in theres and get 14.4 in the1/4 and still can get 25 mpg. plus the factory and many mags clame .86-.87g's with its stock full indipendant suspension.
with out any mods im sure these cars would compare nicely with the old muscule and I know the can saprise most imports.so you can say muscule cars have come a long way.
