"This is the biggest and worst crate engine we have ever built."

Chevrolet has just launched the largest and most powerful crate engine ZZ632/1000 in its history. The company revealed in a press statement that the naturally aspirated 10.4 liter (632 cubic inches) V-8 engine can produce 1,004 horsepower and 876 pound-feet of torque. 

According to Chevrolet, Big Block V-8 can reach 1,004 horsepower at 6,600 rpm, and the speed reaches the recommended maximum of 7,000 rpm. The automaker explained that fuel is pumped into the engine through eight-port injectors, and the machine breathes through high-flow aluminum cylinder heads on CNC machine tools. These cylinder heads are all the same size to ensure that they all provide similar power.

The new crate engine shares the same mold with Chevrolet Performance’s 9.5-liter ZZ572 crate engine-for the COPO Camaro-although the casting has been adjusted to accommodate a displacement of 632 cubic inches. For reference, COPO Camaro ZZ572 is Chevrolet’s largest engine ever. Its power is so powerful that COPO is not legal on the streets.

Chevrolet explained in its release that the ZZ632/1000 covered more than 200 simulated resistance bands on the dynamometer. The automaker also announced that it will showcase its new crate engine at the 2021 SEMA show at the Las Vegas Convention Center next month. The company has not disclosed the pricing of the new engine, but as The Drive pointed out, the retail price of the automaker's ZZ572 engine is approximately $16,000. The company did say that delivery is scheduled to begin early next year, so the company will not be too far from revealing the pricing of this beast engine.

"This is the biggest and worst crate engine we have ever built," Russ O'Blenes, Director of General Motors' Performance and Racing Propulsion Team, explained in the company's statement. "As the king of performance, the ZZ632 is at the top of our unparalleled crate engine series. It provides incredible power, and it relies on pumping air."

The introduction of the powerful internal combustion engine is in stark contrast to parent company General Motors' plan to achieve full electric power by 2035. The company recently launched a new Ultium series electric motor, which will provide 1,000 horsepower for the electric Hummer.
