Just last week, Chevrolet Performance unveiled the ZZ632, the biggest, most-powerful crate engine the brand has ever offered. Now, we have new pricing information on the monster motor, which starts at a suggested retail price just under $38,000.
Per a recent online listing from Gandrud Chevrolet in Green Bay, Wisconsin, the new Chevrolet Performance ZZ632 starts at $37,758.72. However, Gandrud Chevrolet currently offers it on sale through its website with a listed price of $29,499.
That certainly isn’t chump change, especially for a performance crate motor. Nevertheless, the ZZ632 Big Block justifies the cost with a long list of impressive features and specs, starting with the output. Peak horsepower is rated at 1,004 ponies at 6,600 rpm, while peak torque is rated at 876 pound-feet at 5,600 rpm. Both figures are on 93-octane gasoline. Redline is recommended at 7,000 rpm.
That’s a lot, especially from a naturally aspirated engine. The raw cubic inches make the ZZ632 a whopper of a drag racing motor, and according to Chevrolet Performance, a single example of the engine endured more than 200 simulated drag racing passes on a dynamometer during the development process.
The ZZ632 is based on a cast iron block with CNC-machined aluminum heads. Standout features include four-bolt main caps, a forged steel crankshaft, forged steel connecting rods, and forged aluminum pistons, with the compression ratio set at 12.0:1. The iron block shares the same mold as Chevrolet Performance’s ZZ572, with bore increased 0.040 inch, and stroke increased 0.375 inch. Eight electronically controlled port injectors provide the fuel.
The heads incorporate an RS-X Symmetrical Port design with symmetrical intake and exhaust ports to ensure that all eight cylinders yield similar power output. There’s also a billet steel hydraulic roller camshaft, crank-trigger ignition system with coil-near-plug ignition coils mounted on a unique valley plate.
The new Chevrolet Performance ZZ632 crate engine will be on display at the 2021 SEMA Show in Las Vegas next week, while deliveries kick off next year.

Can I get one with my egg money??? I sell the eggs for only $1299.00 a dozen… Buy lots…
Too expensive. Should be HALF that price.
Wow, that is even more than I expected, I was thinking high 20’s, but GM is proud of those new cylinder heads. I cannot wait to see what the aftermarket does with that cylinder head design, you listening Dick Maskin?
Dang…. I just got a call that Dick passed away 2 weeks ago… What a Terrible year for racing engine builders, losing Sonny Leonard, and Richard (Dick) Maskin in the same year, Literally have tears in my eyes after all the years working with those guys. RIP Dick, I will never forget the great phone calls, friendship, and all the miraculous turnarounds you provided for us over the years, there was nobody better!
Oh I’m dreaming already. Now if I can just find that bundle of cash that’s buried in the back yard. It wolud be a dream in my ’69 Chevelle SS. Gotta beleive!
That is exactly what I said to my 27 yr old son. This engine would drop right into my old 69 Chevelle SS 396 with Turbo 400 automatic. Me being a left leg above the knee amputee my cars are automatics.
Not quite drop right in, ZZ632 is a tall deck, and very tall cylinder heads, and extremely tall intake manifold, will be about 10″ out of your hood, to the top of the butterfly with no air cleaner. The bigger issue in a 69 Chevelle is going to be the headers, as these exhaust ports are about 2″ higher than stock BBC, and spaced differently, so you will need to make custom headers, which will be a challenge in that tight engine bay. The dyno picture here is showing 2 1/2″ primary tube headers which are pretty big in a stock chassis. It would be a tricky build without chopping up the car for header spacing.
Pace Performance $29,499.
This will look inexpensive compared to what an LT6 crate engine, harness, and controller will go for once released.
I do not think you will see LT6 offered as a crate motor. Flat Plane Crank engines have to be mounted in a very special way to dissipate vibrations, backyard mechanics throwing that engine in street rods is not going to produce good results.
If it’s a current production engine, it will be available in some assembly form. An LT6 might not be offered as a Performance Parts kit, but as a current production engine it will be available in some form as a service part. Being a PBC build, likely not a short block, but a long block as minimum and possible full dress. Z06 volume and warranty work will make it difficult for non VIN associated orders, but it will happen. The zz632 being non production and extremely low volume will likely be assembled at PAS in Livonia, and only once ordered by customer.
Ya, will have to wait and see on LT6, I think you are right though on the ZZ632, GM subs many of their HP crate engines to PAS. I ordered a ZZ632 to play with.
Why is this journalist calling this an engine on one line and calling it a motor in the next line? Nowhere in owners manuals do the call the engine a motor. Now with the advent of EV’s…
tonyLakeside: It’s it motor driven or engine driven? Motor news or engine news? It a luxury journalist have, call things as they see it. 😎
Haha, Engines builders and racers almost always call them motors, which is incorrect, but common. Think of it this way, what does “General Motors ” mean?
Really? That’s expensive compared to the Hellephant that costs 8k less.
For a real world comparison, I built a relatively mild 632 for my my ‘68 Chevelle back in 2015. The bottom end was recycled from a well known drag racer (who I promised to keep anonymous). I used an out of the box set of AFR heads, and a fairly tame cam. It makes about 875 horse. I paid no professional to machine anything other than a custom set of pistons, and spent around $18k all in. If you’re not highly knowledgeable and able to make some stuff yourself, you’re going to spend a bunch more, so $30k is not entirely unreasonable. These are not cheap toys.
Biggest RIP off ever. Shafiroff racing has a 598ci, 1005hp BB Chevy for $16,250 with Dart block, Scat steel crank and H- beam rods, Brodix heads and a lot of other quality components.
Support the racers !!!
Ya, that is true. The only thing really cool on the ZZ632 is the cylinder heads, nobody has those yet, but the aftermarket Brodix, AFR, and Dart, will figure it out quickly.
The engine you mention though is 14.5 to 1 compression, carbureted , and conventional MSD ignition. Wont run on 93 octane, and need to know what you are doing to tune it or you will blow it up quickly. GM’s engine is plug and play, for the sportsman racer, and would be an awesome add in the COPO Camaro.
Nobody’s going to buy that engine. People looking for that king of engine build them. This will go the way of the LT5.
Can I stuff one of these in a AWD canyon or Colorado to surpass the YENKO pickup? J. V.
I like the idea of starting from stratch to build your own big C.I. Big Block. It can be done if you can find the “Old guys” who still have the brains to help you out. All it takes is time, money and smarts. Long live the Big Block!
I’m currently running a 598 standard deck height crate motor I bought through Blueprint Engines out of Nebraska. They also do a 632 that’s roughly half the price of this one. They also build power adder motors, that are built for Nitrous or forced induction, that you can throw a pro shot fogger on, and be making a lot more power than this, and with the money you’ll save, you can build a bullet proof drive line to make it all work.
What about Twin-Turbo 4.2L V-8 LTA? Any chance this be tuned /crate engine? Perks? Cons?
Hi I had an engine like that in 1969 in a GMC 9600 COE. It was built to replace the V 12 engine.
It was 637 cubic inches.
I like factory engines , and I imagine there is a race class for these that makes them preffered over homegrown/ built . But coming up with exhaust will be a challenge. I suppose drive line (pinion gears) could be an issue.
Not at all. Mark Williams makes many different rear end set ups that take a neck of a lot more power than this. A rear end is the last of your worries in this case.
Where the uckf is my comment?
Leethal, , your comment is 2nd from the top under “old farm boy”
Not too bad, Just right for my 2015 Camaro ZL1, lots of miles on this beast, need to cash-in a couple of my Bitcoins for the complete update.
Their engineers are spot on for getting the most HP and tech., plug and play all the way. Can’t wait to hear this monster fire, I see new tires in my future.
One of the reasons I bought GM stock in 8-20, keep up the great work guys.
