Corvettes are some of my favorites. The Z06 is a special Corvette as it is the lightest of all Corvette models, has the largest-displacement small-block ever produced in the form of a 427 cubic inch (7.0 L) LS7 engine, with a dry sump oiling system, and connecting rods made out of titanium alloy. The frame of the Z06 is constructed from aluminum, saving 136 pounds over the standard steel frame.
