The '60s and '70s of America are known for producing some of the most excellent muscle cars of all time. A few of the rarest muscle cars came into being during this time, packing giant torque-rich V8s. Regulations regarding emissions and other issues ended up taming the cars in the 1980s and onwards. This is why there was an immense amount of horsepower in cars only up to the 1970s.
An admiration for fast muscle cars has created a niche market of car collectors. The classic “muscle car” in the United States was a sports coupe with a “super-sized” engine and two doors, which would deliver high-performance driving. These vintage vehicles began to show up in the 1940s, and most of them possessed V8 engines. If you are interested in learning about the fastest muscle cars to have ever existed, this is a list you are sure to appreciate.
