1970 Mercury Cyclone Spoiler Boss 429 – 370 Horsepower

Although Mercury went neck and neck with Ford through much of the muscle car golden age thanks to Ford's hot engines, its models weren't really exciting compared to the best '60s and '70s muscle cars. That changed in 1970 when Mercury introduced the brand's best-ever muscle car, the Cyclone Spoiler.

It featured a unique body and styling (similar to the fastback Ford models), black or white stripes, front and rear spoilers and a hood scoop for ram air intake. Mercury added a sleeker front section to make it more aerodynamic at high speeds. Standard in the Mercury Spoiler was a 370-hp 429 cu-in V8 engine.
