Chevrolet Performance has introduced a new large ZZ632 V-8 crate engine with a displacement of 632 cubic inches or 10 liters, among which, production, waiting for it, is slightly more than 1,000 horsepower and 876 pound-feet of amazing torque.

Chevrolet has been in control of the crate engine industry for the longest time, but it hasn't really appeared in the news for some time. Now with the return of the bow tie brand, the situation has changed. In the past two years or so, the Internet has been full of stories about the exchange of 1,000-horsepower Ford Performance’s 7.3-liter Godzilla V-8 and 1,000-horsepower Mopar Hellephant.

With the debut of this new 1004 horsepower, 10.4 liter ZZ632 crate engine, Chevrolet Performance reminds us why they dominate the crate engine market. The new ZZ632 does not use forced air, turbocharging or superchargers. Instead, the engine only relies on huge displacement to provide big data.

ZZ632 uses cast iron cylinder structure, four-bolt main cover, forged steel crankshaft, connecting rod and forged aluminum piston, with a compression ratio of 12.0:1. It is worth noting here that the iron block is based on the same mold as the ZZ572 crate engine, and the casting is now processed into a displacement of up to 632 cubic inches.

Compared with the 572 cubic inch ZZ572 V-8, the bore is also increased by 0.040 inches, and most of the displacement gain comes from the longer 0.375 inch stroke. In order to adapt to the long stroke, both the slider and the connecting rod must be redesigned from the beginning.

This Big Block V-8 can generate peak power at 6,600 rpm and can accelerate up to 7,000 rpm. The highlight is the refueling system of ZZ632, which consists of an eight-port fuel injector and a CNC machined high-flow aluminum head. The cylinder head has symmetrical intake and exhaust ports to ensure that all cylinders produce the same power.

These RS-X symmetrical port cylinder heads are named after powertrain engineer Ron Sperry, who developed it as one of his last victories after studying GM performance and racing engines for more than half a century. Sperry also added symmetrical ports to Chevrolet's classic Small Block V-8 engine, which was introduced on the Vette in 1997.

There is no news about the pricing yet, although the 621-horsepower ZZ572/620 that shares an engine block mold with it is priced at $16,304.82. ZZ632 will be sold through Chevrolet's Performance dealer network from early next year. It will be exhibited at the SEMA show in Las Vegas from November 2 to 5 this year.

Well, with the launch of ZZ632, I guess Chevrolet will stick to the old saying "there is no replacement for displacement". Oh, I completely forgot to mention the best part of this new engine. It can generate all this power while using the 93-octane old fuel provided by the local gas station.

What is this talking about now, isn't it? I want to know what kind of performance the hot rod and tuner can get from this new bulky V-8. Only time will prove everything, but exciting moments await ZZ632, and we can't wait to see it appear on the drag belt soon. Expect it to be reliable, because Chevrolet ran the ZZ632 for 200 simulation test cycles and the engine did not sweat.

Chevrolet Performance today launched the ZZ632/1000* crate engine-the largest and most powerful crate engine in the brand's history. The naturally aspirated 632 cubic inch V-8 produces 1,004 horsepower and 876 pound-feet of torque.

"This is the biggest and worst crate engine we have ever built," said Russ O'Blenes, Director of General Motors' Performance and Racing Propulsion Team. "As the king of performance, the ZZ632 is at the top of our unparalleled crate engine lineup. It provides incredible power, and it is achieved by pumping air."

The Big Block V-8 reached peak power at 6,600 rpm and the speed reached the recommended maximum of 7,000 rpm. Fuel is provided by eight-port injectors, and the engine provides symmetrical ports through CNC-machined high-flow aluminum cylinder heads. Although the shape of the intake port of the traditional bulk design varies from cylinder to cylinder, all eight intake ports of ZZ632 have the same length, volume and layout. Similarly, all exhaust ports of ZZ632 are the same. This symmetry ensures that each cylinder produces similar power.

These RS-X symmetrical port cylinder heads are named after powertrain engineer Ron Sperry, who designed it as one of his final achievements in more than 50 years of GM performance and racing engines. Sperry also introduced symmetrical ports for Chevrolet's iconic Small Block V-8, which was equipped with the Gen III LS1 engine that debuted in the Chevrolet Corvette in 1997.

The iron block of ZZ632 shares a mold with Chevrolet Performance's ZZ572 crate engine, but the casting is processed to fit the huge displacement of 632 cubic inches. Compared with the 572 cubic inch V-8 engine, the bore is increased by 0.040 inches, and most of the displacement gain comes from an increase in stroke of 0.375 inches. To provide clearance for long strokes, engineers modified the slider and connecting rod. The four-bolt main cap and forged rotating components ensure strength and durability. During the development process, an engine has undergone more than 200 simulated drag belt tests on a dynamometer.

The ZZ632/1000 crate engine will be exhibited at the 2021 SEMA show in Las Vegas from November 2 to 5. Chevrolet Performance dealers will begin deliveries in early 2022.
