Now THIS, is something special indeed!!! The 1969 Hurst Oldsmobile 455!
The very reputable and knowledgeable autoweek.com, says that when introduced as a 1968 model, the 455 was a 442 on steroids. Some fan sites say the drivelines were installed at the factory, but conventional wisdom has it that Lansing, Mich., industrialist John Demmer was tapped to build the cars offsite to circumvent General Motors’ 10-pounds-per-horsepower mandate. Either way, all agree that the production cars were based on a prototype conceived by Hurst and perfected by Jack “Doc” Watson.
