The Silverado 427 is powered by GM Powertrain's 7.0-liter LS7, the same Gen IV small-block V-8 that is the center of power in the Corvette Z06 and available as a "crate engine" package from GM Performance Parts. Its cubic-inch displacement is 427. A six-speed manual transmission backs the engine, providing the driver with full control of the vehicle's substantial capability.
he Silverado 427 is a total performance package, with a lowered suspension that delivers racecar-like reflexes and an exterior styling package that is simultaneously aggressive and understated.
