My 2007 Z06 Thank you for stopping. Front view,very cool for that 427 alum block. 505 HP Nice Nice rear end Corvette Racing Notes The C6.R is the most technically advanced sports car ever developed by GM, combining lessons learned in the dominant Corvette C5-R with the advanced technology of the Corvette C6 and Z06 production models. The Corvette C6.R race cars are the products of rigorous testing and development. The rulebook requires close adherence to production specifications, and the Corvette C6.R race cars have strong links to their showroom counterparts. 2006 marks Corvette's 50th anniversary in international road racing. John Fitch and Walt Hansgen drove a Corvette to a ninth-place finish overall and a Class B victory at the 12 Hours of Sebring in 1956, the first step onto the world stage that established Chevy's sports car as a contender in top-level competition. The Corvette C6.R's roots reach to the Corvette assembly plant in Bowling Green, Ky. The same hydroformed steel frame rails used in production Corvette coupes and convertibles provide the foundation for the racing version. Corvette Racing's C6.R race cars are powered by race-prepared LS7.R small-block V-8 engines. The GM small-block V-8 is America's most popular and most successful production-based racing engine. Total production of GM small-block-based engines is approaching 90 million units. This motor has powered more winning race cars and won more championships than any other engine in American motorsports.
