Deliveries will begin in the early part of next year.
Over the last few years, the crate engine market has seen a revival. Since November last year, Dodge has been selling the Hellcat Redeye engine V8. Ford is developing a twin-turbo Godzilla engine to compete. Even Honda was able to enter the market with its Civic Type R crate-engine, and Chevrolet now has its largest and most powerful engine. The Chevy ZZ632/1000 engine is here, ladies and gentlemen.
These numbers are amazing, Chevrolet. The Big Block V8 engine, with a displacement of 632 cubic inches (10.35 liters), produces a peak output power of 1,004 horsepower (738 Kilowatts) as well as 876 pound-feet (1.188 Newton-meters), when it is running on 93-octane gasoline. These figures can be reached at 6,600 rpm which is close to the maximum recommended speed of 7,000.
According to the manufacturer, all eight intake and exit ports on the ZZ632 are the same length, volume and layout. This is in contrast to Big Block engines that have noticeable variations in the port shapes from cylinder to piston. Eight port injectors deliver fuel to the cylinders and Chevrolet claims that all cylinders have the same power.
Chevy’s new crate engine shares its mould with the ZZ572 engine from COPO Camaro. However, the ZZ632’s castings are machined to support the 10.35-liter displacement. The bore is 0.040 inches larger than the 9.4-liter V8. Chevrolet claims that it thoroughly tested the new crate engine with just one engine covering over 200 simulation drag strip passes using a dynamometer.
Russ O’Blenes from Chevy’s Performance and Racing Propulsion Team comments, “This is our biggest and most dangerous crate engine ever made.” The ZZ632 is our king of performance crate engine lineup. It produces incredible power and can run on pump gas.
The new crate engine will be on display at the 2021 SEMA Show next month. Chevrolet has not yet revealed the price, but customer deliveries are expected to start in early next year.
