The 57 chevy was not a muscle car and really isn't one. The are more hot rod since it never had a large engine with alot of horsepower. The cars of that era aren't the only muscle cars. The 1985-87 buick grand national and Monte carlo SS were some of the last muscle cars made. The buick doesn't have a large v8, only a Turbocharged and Intercooled 3.8l V6. People who know what a GN is and have ever tried to run one or have driven one know it is a true muscle car. The last gen Camaros/TAs, and mustangs are pony cars and aren't really considered muscle cars. New mustangs are gay as hell anyway. What kind of sports car makes less than 260hp? That's the most the mustang GTs ever made from the early 90s till 2005. They suck.
