As if the Shelby Cobra 289 wasn't fast enough, Carroll Shelby went one better in 1964 and introduced the Cobra 427 with a seven-liter V8 and over 400 hp. This sports car was actually supposed to dominate the racetracks, but the number of units required for homologation was missed, so most of the cars were sold as "softer" road versions. However, "gentle" was not to be taken too literally, as a test drive with an original Cobra 427 shows.
