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.
