1000 forces in a box under the door


American brand Chevrolet presents “the biggest and coolest” ‘box engine with 1004 hp. The start of sales of new items should start early next year.

The market for so-called “box” engines has undergone something of a revival over the past couple of years. Dodge has been selling the Hellcat Redeye V8 engine since last November, while Ford is reportedly developing a twin-turbo Godzilla engine as a competitor. Even Honda entered the market with the Civic Type R engine, and now Chevrolet is introducing its largest and most powerful body engine to date. Ladies and gentlemen, welcome the Chevy ZZ632 / 1000 engine.

The numbers shared by Chevrolet are impressive.

The Big Block V8 engine has a displacement of 10.35 liters, and develops a maximum power of 1004 horsepower (1188 Nm) when running on gasoline with an octane rating of 93. These figures are reached at about 6600 rpm, which is very close to the recommended maximum of 7000 rpm.

The manufacturer proudly explains that all eight intake and exhaust ports of the ZZ632 engine are the same length, volume and layout, unlike other engines in the Big Block family, which have noticeable differences in the shape of the ports from cylinder to cylinder. Meanwhile, fuel is delivered to the cylinders using eight-way injectors, and Chevrolet claims all cylinders produce the same power.

Chevy’s new “box” engine is structurally similar to the ZZ572 engine from COPO Camaro.

“This is the largest and coolest box engine we’ve ever built,” comments Russ O’Blens, director of the Chevy’s Performance and Racing Propulsion Team. “The ZZ632 is at the top of our unprecedented line of similar engines and is the king of performance. It delivers incredible power and does so with the pumped gas. ”

The automaker will unveil the new “box” engine at SEMA 2021 next month. Deliveries to customers are slated to begin early next year, although Chevrolet has yet to disclose pricing.
