A Procharger-blown C7 Stingray and a nitrous-fed, stroked 455 C6 Z06 lined up on a public street in Mexico for a 60-to-190-mph roll race, and the gap between them stayed close for nearly the entire run. Built and driven by 1320video regular StangKiller, the C7 represents the newer chassis and forced-induction school of Corvette tuning, while the C6 leans on raw cubic inches and instant nitrous torque. Watch to see which small-block philosophy actually crosses the line first.
