The most powerful of the bunch is a 1973 Chevy Chevelle Laguna packed with the LT5 supercharged 6.2-liter V8 from the new Chevy Corvette ZR1. Like in the ‘Vette, the engine makes 755 horsepower and 715 pound-feet of torque. It packs a larger displacement supercharger relative to the LT4 found in the Corvette Z06, Camaro ZL1 and Cadillac CTS-V. The Chevelle itself sports a carbon-fiber hood, new front and rear spoilers, a modified suspension and NASCAR-style 18-inch wheels wrapped in Goodyear tires.
The other two vehicles GM is bringing are both trucks. The first is a 1967 Chevy C10 with a ZZ6 EFI crate engine. It’s basically a classic 350 Chevy small block fitted with a modern electronic fuel-injection system. The engine comes in various tunes making up to 420 horsepower. The C10 itself packs lowered suspension, 20-inch wheels, a revised tailgate and rear bumper and a custom interior. Chevy hasn’t released any photos, so we’ll have to wait a few weeks to see the full truck.
The final vehicle on display will be a 1978 Chevy K10 Silverado with a L96 crate engine. The 6-liter V8 is rated at 360 horsepower and 380 pound-feet of torque. Chevy says the main benefit of the new electronically-controlled fuel-injected V8 is more power and less weight than classic Chevy big blocks. The engine is paired with a four-speed automatic. The K10 was reworked with a frame-off restoration at GM’s Milford Proving Grounds in Michigan.
