If you love speed, then the 1960s and 1970s was a great time to be alive. This era of power created some of the rarest muscle cars packing giant torque-rich V-8s. Emissions and other regulations would tame muscle cars in the 1980s, but these aging beasts of the road still come with some surprising stories as well as some surprising horsepower.
1966 Shelby GT350
The legendary 1965 Mustang Shelby GT350 were serious high- performance machines. In fact, some buyers that very first year felt these cars were a little too hardcore and at the same time Shelby was on a rampage to cut costs. So, for 1966, Shelby replaced, deleted or made optional some of the car’s signature high performance features like the adjustable Koni shocks, the fiberglass hood, free-flowing (and loud) side exhaust outlets and that fully locking Detroit Locker rear differential.
Little Known Fact: But if you checked the fine print there was a Paxton supercharger option available for 1966. The $700 option was claimed to boost the 289 cid V8’s 306 hp output by 46 percent. That’s probably a bit generous, but it was still an excellent power adder. But the supercharger cost nearly a quarter of the car’s original pricetag and just 12 customers were willing to pay.
