Chevrolet Performance Unveils 1,004-Horsepower ZZ632 Crate Engine

Earlier this week, Chevrolet Performance teased us with a brief video overlaid with the sound of some impressive internal combustion noise. Now, the go-fast brand has pulled the sheets on the source of that soundtrack, namely the new Chevrolet Performance ZZ632 crate engine.
Framed at the largest and most powerful engine Chevrolet Performance has ever made, the ZZ632 create engine produces a head-spinning 1,004 horsepower and 876 pound-feet of torque when fed 93-octane gasoline. Peak power arrives at 6,600 rpm, while peak torque arrives 5,600 rpm. Redline is recommended at 7,000 rpm.
“The ZZ632 sits at the top of our unparalleled crate engine lineup as the king of performance,” said director of the Performance and Racing Propulsion Team, Russ O’Blenes. “It delivers incredible power, and it does it on pump gas.”
Highlights include eight port injectors and CNC-machined high-flow aluminum heads. The heads are equipped with symmetrical intake and exhaust ports, thus ensuring all cylinders produce the similar power output. The technology is dubbed RS-X Symmetrical Port cylinder heads as a nod to Ron Sperry, who also designed the symmetrical ports on the Chevy Small Block Gen III LS1 V8 cradled by the 1997 Chevy Corvette.
The ZZ632 includes a cast iron block, four-bolt main caps, a forged steel crankshaft and connecting rods, and forged aluminum pistons. The compression ratio is 12.0:1. Notably, the iron block shares a mold with the Chevrolet Performance ZZ572 crate engine, with the castings machined out to the impressive 632-cubic-inch (or 10.3-liter) displacement. Bore is up 0.040 inch, while stroke was increased 0.375 inch. Both the block and connecting rods were modified to accommodate the extra-long stroke.
According to Chevrolet Performance, a single example of the ZZ632 endured over 200 simulated drag-racing passes on a dynamometer during development.
As expected, the Chevrolet Performance ZZ632 crate engine will make an appearance at the 2021 SEMA Show next month. Deliveries are expected to ramp up early next year.

So is this considered balanced and blueprint
Crate
Interesting comments on here, looks like a pretty stout engine 1.58 hp per cube is no slouch.
All things considered.. impressive
Well… I don’t need it . Have nothing to drop it in . But I do want it ….
What is the ignition set up? Distributer, computer, ?
Donavan, your an idiot.
Yeah the engine doesn’t start to pull until 3000, but at 3000 it’s damn near making as much power as an l86 at peak.
All high horsepower engine are race engines. I don’t care if you were born out of the backside of an eco turd, the fact that your pushing and trying to convince everyone it’s stupid speaks volume of your ignorance.
Engineering. Anything can be done with enough money. But not at your little motor shop.
OK now all I have to do is find a Vega or Chevette to cram this into!
I’ll stick with my turbskees and spooterchargers, get the same to 150% the horsepower and still be able to run on the street, even if I never get to pass up a gas station. Added bonus with the spooter is that I don’t have to wait for the feels. lol
The ZZ632 / 1000 is again a masterpiece from Chevrolet Peformance for SEMA 2021.
If you consider that the engine delivers 1004 HP at only 6,500 RPM (see diagram) and 876 LB-FT torque at 5,600 RPM, it is of course very elaborately designed for 100HP per liter and therefore of high quality if it holds at least 200 drag starts.
You have to consider that the ZZ632 achieves this performance at regular speeds as with series engines.
This is an absolute technical masterpiece of the developers and also the engine builders who assemble this ZZ632 super engine.
The price of the ZZ632 is also calculated by marketing and should be under $ 20,000 + tax.
Conclusion: Again you can see that GM has always had great ideas and that they are implemented quickly so that customers can buy top products.
Could also imagine a BossHoss V8 motorcycle for marketing activities.
I was wondering how it would work in my boat. Although I might need to double or triple the fuel tank size. LOL
To V8srule Amen to that bro.
After reading many media reports and comments, I am now going to write another comment.
The ZZ632 / 1000 crate engine is currently the best of all times and, as known at GM, also durable and inexpensive. Since I assume that fans will buy the V8 engine, few will be built too cult. Think you can drive this engine at regular speeds in vehicles with manual transmission. The durability of the clutch and gearbox also depends on the weight of the vehicles. I think show trucks and show cars like Cadillac from the 50s to 90s are perfectly suited.
And whoever thinks the ZZ632 / 1000 is not ecologically correct, I clearly write that he is wrong because even the exhaust gases can be clean! The exhaust sound of a 10.4 liter V8 has to be brilliantly powerful. I wish for really nice restomods read show cars. The weight and power of the ZZ632 / 1000 is technically not an issue because the ZZ572 was also installed in vehicles.
Since they don’t like diesel trucks in California, the ZZ632 / 1000 can also be installed in class 3-8 trucks!
Since it has no turbocharger, it also runs cooler and produces less heat!
Addressed to the German media such as AMS – stay with your mass-produced 4.0 – 4.4 BiTurbo V8 which are scrap after 50,000 miles and cost twice as much as the ZZ632 / 1000.
The ZZ632 / 1000 is awesome as I wrote before. The cost of the engine too.
I would be interested in whether it is possible to develop and produce a crate engine with identical cylinder heads (mirrored left and right)?
An example where this was possible is the BMW V12, M70B50 engine.
This should really be possible in 2021 and the costs would be much lower because only one cylinder head! This applies to the entire process from planning, purchasing, development, part numbers, production, sales, logistics and maintenance!
Why this question? I am a fan of sensible cost down thinking!
The last time I checked Big Block Chevy heads were interchangeable between left and right. And that is the architecture this is based on.
Why or how can someone state you can’t afford it ? Easy… Cuz they can’t ! Don’t waste your time on them .
After reading these comments I bet most of you all drive a cruise and are just bench racers
Love to put it and the trans in my 94 Yukon..
