Chevy Performance has announced a new ZZ632 naturally aspirated crate engine with 1,004hp. https://gmauthority.com/blog/2021/10/chevrolet-performance-unveils-zz632-crate-engine/ I'm guessing it may be the last big power IC engine from GM, as things all go electric.

"Endured 200 runs on drag strip"
So a total of what, a few hours of runtime?
Id be more impressed by a crate motor that was built for durability and power. Something that could run at 7000rpm for hundreds of hours.
In reply to pheller :
Ballparking a 10-second run, that's just over 1/2-hour total, not counting idling/testing/tuning. So yeah, probably a couple hours max.

They could make that 1000hp engine last that long, but you wouldn't like the price or maintenance requirements. Just how it works. But what's the use case?
Even race engines, in real race cars don't run at redline for "hundreds of hours."
Are we seriously bagging a car company for lack of reliability data on a 1,000 HP crate engine?
I'm pretty sure engine life in this is going to be application specific so it may be a little tough for the manufacturer to pin down something better than "200 simulated drag passes on a dyno"
Let's all cheer up a shade and appreciate that someone is making anything like this.
Drag engines in the 600+ci range make a lot more than 1000hp, it's going to be too high strung to use as a tow rig...
i agree, not going to be concerned with power duty cycle, since it's basically a street rod engine.
In reply to z31maniac :
No but a GM / Mercury marine production engine did it for 24 hrs once and set a whole bunch of land speed records. Then a VW one off prototype was built to break all those records several years later.
There are engines that can handle that type of abuse but very few crack that hp. You can win 24 hr races on less power for sure.
Guaranteed to last decades in the trailer queens that it'll get installed in....
And nearly just as long in the weekend driver that only gets above 4000rpm for the occasional burn out.

"Aside from the discontinued supercharged LT5, which put out 755 hp, the biggest mill Chevrolet Performance offered was the naturally aspirated ZZ572 big-block. This Dominator-fed big-bore beast pumps out 727 hp and 680 lb-ft of torque. Four-bolt mains along with forged internals gives it strength, and a pair of high-flowing 310cc heads combined with a solid-roller cam help the good times roll. The ZZ632 adds 60 cubic inches to the party and makes an additional 277 hp; even better, it does it on 93-octane pump gas!"

Pretty freakin impressive to me!
A decade or so ago, World Products had a 632 crate engine with a two year 24,000 mile warranty, but it wasn't a kilo-horse engine.
I'd like a 632, if only because 632 rolls off the tongue nicely.
Yes, I imagine many of them will end up in high end street machines that will probably never put them to full use except for the occasional smoky burnout (watch the TV car shows next year) but it is an impressive motor. The big crate engines from Mopar and Ford are supercharged while this one is naturally aspirated, which makes it even more impressive.
I love that that power number can be expressed as 10 to the power of 3 horsepower.
And that it's 10 freaking liters of displacement.
I wonder if Mrs VCH would notice if one ended up in her Camero...

I think she'd figure it out pretty quickly...

I guess $30k.
C&D's article said that the next motor down the list was 16k. I'mma guess 20.

I mentioned it to her, and gave her the context that it would be almost double the size of the engine currently in there. To which she replied, "so...it would get...7 miles to the gallon?"
I think that earned her a hard pass.
Ford: *unzip...thud* Godzilla 445 ci, 430hp
SRT: *unzip...thwap* Hellaphant 426ci, 1000hp
GM: *unzip - THUMP* ZZ632, 1004hp
