I don't have anything against them at all....they're just not muscle cars, they're sports cars. There IS a difference between the 2. Muscle cars= little car, BIG ASS ENGINE. Biggest engine to ever come in a mustang back in the day was a 351 Cleveland. Now I know I'm gonna catch flack from the rest of the car guys because "oh thats not true, they had 428s and 429s in them too" well yes..this is true..BUT..they were originally designed as a standard sports coupe. The original muscle car was the 1964 Pontiac GTO, and packed a 389 Tri-Power engine, in a 3000 pound car, that thing was a rocket.
