Shelby designed its own coil-sprung chassis, and fit the massive Ford 427 V8 to create the incredible Cobra 427. It's still one of the quickest cars ever built and it's somehow still in production today.
Porsche built 25 917s for homologation in 1969. It won Le Mans in 1970 and 1971, only losing when the rules changed. The 917 still holds the Le Mans fastest lap record.
