What is the top speeds for a muscle car?

There's no single top speed for "muscle cars" because it's a broad category encompassing many models with vastly different performance capabilities across different years. Top speed depends heavily on:

* Year of manufacture: Older muscle cars generally had lower top speeds than modern ones.

* Engine size and modifications: A stock 426 Hemi Dodge Charger will have a different top speed than a mildly modified 350 Chevy Camaro, and both will be vastly different from a heavily modified car.

* Gear ratios: The transmission gearing significantly impacts top speed.

* Aerodynamics: Body design affects how much air resistance a car experiences.

To give you some *examples* of top speeds, a stock 1969 Dodge Charger R/T might have a top speed around 130 mph, while a modern, heavily modified muscle car could exceed 200 mph. A stock late-model Mustang GT or Camaro SS would likely be in the 150-160 mph range. These are estimates and can vary based on the factors listed above. You'd need to specify a *particular make, model, and year* to get a more precise answer.
