That 427, as most small-block fans will recognize, is the cubic-inch displacement of GM’s 7.0-liter race-bred LS7 V-8, and the engine’s application in the Corvette convertible makes this particular ‘Vette an instant classic.
Peak output remains at 505 horsepower and 470 pound-feet of torque, and just like in the Z06, where the Corvette 427 Convertible gets its engine, a six-speed manual is the only transmission option.
In addition to the engine, the Corvette 427 Convertible also picks up the Corvette Z06’s driveline and rear axle system and latest-generation Magnetic Selective Ride Control. The standard 19-inch front and 20-inch rear wheels are wrapped in ZR1-style Michelin PS2 tires and are the machine-face Cup type introduced last year. Black Cup wheels or chrome ZR1-style wheels are also available.
The Corvette 427 Convertible also features several carbon fiber components that help reduce weight, including the hood, fenders, and floor panels. Buyers can also opt for a “CFZ” carbon fiber front splitter and set of rocker panels.
In case you’re wondering, the final curb weight of the new special edition is 3,355 pounds, which means the car has a power-to-weight ratio of one horsepower for every 6.64 pounds of vehicle mass. The combination of low mass and high output should make the Corvette 427 Convertible one of the fastest drop-tops in the world, with estimates coming in at 0-60 in 3.8 seconds, quarter-mile performance of 11.8 seconds, lateral acceleration of 1.04 g and a top speed of more than 190 mph.
All 2013 Corvette 427 Convertible will carry a unique vehicle identification number sequence, similar to the Corvette ZR1. And if you’re interested, you better act fast as this model is likely to run out quick and we’re not sure when Chevrolet is likely to offer another.
