Chevrolet has just launched its biggest and most powerful crate engine ever, the ZZ632/1000. The naturally aspirated 10.4-liter (632-cubic-inch) V-8 engine produces 1,004 horsepower along with 876 lb.-ft of torque, the company revealed in a press statement.
The Big Block V-8 reaches 1,004 hp at 6,600 rpm and it goes up to the recommended maximum of 7,000 rpm, according to Chevrolet. Fuel is pumped into the engine by eight-port injectors and the machine breathes through CNC-machine high-flow aluminum cylinder heads whose measurements are all the same, ensuring they all provide similar power, the automaker explained.
This engine has the same mold as that of the previous Performance’s 9.5-liter ZZ572 crate engine — which is used in the COPO Camaro — though the castings are adapted to accommodate the 632-cubic-inch displacement. As a point of reference, the COPO Camaro ZZ572 was the largest engine ever placed in a Chevrolet vehicle, and it is so powerful that the COPO isn’t street legal.
This new crate engine covers more than 200 simulated drag strip passes on a dynamometer. It will be exhibited at the 2021 SEMA show taking place at the Las Vegas Convention Center next month. The price of the engine is yet to be revealed. The Drive points out, the automaker’s ZZ572 engine retails at around $16,000. The deliveries will be starting from next year. Hence, the prices will be revealed soon too.
“This is the biggest, baddest crate engine we’ve ever built,” Russ O’Blenes, GM director of the Performance and Racing Propulsion Team, explained in the company’s statement. “The ZZ632 sits at the top of our unparalleled crate engine lineup as the king of performance. It delivers incredible power, and it does it on pump gas.”
This engine’s launch is opposite to that of the GM’s plans to go all-electric by 2035. The company recently introduced its new Ultium series electric motors, which will provide the electric Hummer with 1,000 horsepower.
