The C6 Z06 arrived for 2006 and is the lightest of all Corvette models. From the factory it came with a hand-built 7.0-liter LS7 rated at 505 horsepower, with dry-sump oiling and titanium connecting rods. The Z06's aluminum frame saves 136 pounds over the C5's steel frame. The one we have is a 2007 Z06 in black with a manual gearbox. It carries a fully built Thompson Motorsports engine, with low mileage and mint condition.
