"Big Chevrolet engine!!!" The press release said so much. It's weird, I thought; Chevrolet is a tight-lipped company, what makes them crow like this? Then I read the numbers. After I regained consciousness (I think my head hit the edge of the table before hitting the floor), I could only mutter to myself: "Big Chevrolet engine!!!"
There are two big numbers here. The first one is 632. This is the displacement of this new monster V8 plant from The Bowtie Boys: 632 cubic inches. That is more than 10 liters. That's huge. But this is not really a big number. The real big number is 1,004. This is the horsepower output. over a thousand! Add 876 pound-feet. Torque makes the naturally aspirated ZZ632/1000 the largest and most powerful crate engine in Chevrolet history.
"This is the biggest and worst crate engine we have ever built," said Russ O'Blenes, director of the General 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."
Gasping, I think? What effect does it have on competition oil? What effect does this thing have on AV gas? Then my thoughts really started to accelerate. How strong is the bottom line? How much can be compressed? How big a blower can be used? What is the size of the block and can you fit it into Gen 1 Nova? Then I calmed down and realized that I must finish writing this article. I can call my drag racing friend later.
The Chevrolet Performance ZZ632 crate engine reaches peak power at 6,600 rpm and the maximum speed is 7,000 rpm. The torque peaks around 5,600 rpm, providing a fairly compact but useful power band. Again, something tells me that you will not use ZZ632 to run around on your favorite mountain roads. Someone told me that this scene is more like "green light! Get it done!"
Now check the details of the refueling and head design. The gas is delivered by an eight-port injector, and the engine breathes through a CNC-machined high-flow aluminum cylinder head with symmetrical ports. These RS-X symmetrical port heads are named after Ron Sperry, a powertrain engineer. Yes, that Ron Sperry. Those who designed them for Chevrolet’s iconic Small Block V8 were equipped with the Gen III LS1 engine that debuted in the Corvette in 1997. Although the traditional design of Big Block differs in the port shape of different cylinders, 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. It also ensures that (if you think about it ahead of time) it is easier to adjust in terms of high-capacity racing car refueling systems.
The blocks of ZZ632 are cast iron, which is a shame, in terms of weight, but I bet the alloy blocks will be blown away by the 100-foot mark. The interesting thing about the ZZ632 block architecture is that it shares a mold with the Chevrolet Performance ZZ572 crate engine. Chevrolet punched a 0.040 inch hole in the 572, and then they punched it 0.375 inch.
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 withstood more than 200 simulated drag belt tests on a dynamometer.
The Chevrolet Performance ZZ632 Crate Engine will be on display at the 2021 SEMA show in Las Vegas starting on November 2nd. Chevrolet Performance dealers are expected to receive deliveries in early 2022, which means SEMA 2022 will be ignited! In the meantime, please check the full specification table below. I have to calm down and call a friend of mine in Woodburn.
