New Corvette Grand Sport gets a new LS6 V8, raising the floor for the American supercar. The new engine is 6.7L in capacity, has a 13.0:1 compression ratio, larger 95mm throttle body, tunnel-ram intakes, a new lubrication system with a second oil feed, forged pistons and rods, and reworked exhaust manifolds. All of that adds up to 535 hp and 520 lb-ft of torque, making this the highest power and torque outputs for an NA Corvette.
