Chevy's 1000HP Crate Engine EXPLAINED

Thanks to Valvoline for sponsoring today's video! To learn more about their incredible Zerex Anti-Freeze, click here: team.valvoline.com/zerex-anti...
Your favorite car companies sell lots of stuff besides cars. You can get Porsche ice cube trays, Audi: The Board Game, or Bluetooth speakers that sort of look like a Lambo. Those’ll set you back $25,870. But for just a little more, Chevy will sell you a 1,000hp, ready-to-run engine, that’s a hell of a lot louder than those speakers. Today is all about the ZZ632: the baddest big block ever. We’re gonna figure out how it makes crazy power, and why an engine with roots in the 1950s won a best new product award at SEMA 2021. Let’s go!

Blueprint makes a 632 with a warranty that crushes the GM on price. At current market value its 15.5k for a fully dressed ready to run 632 that will run on pump gas. There is nothing that will remotely come close to that value in a crate. There are tests of that specific motor making 850 out of the box and has survived dyno pulls north of 2k with 22-24psi of boost.

Fuel consumption at light throttle will be very bad also. I have a 800hp FG Falcon daily, that could be 1200hp just with stronger rods. There is no way I would install this ancient 60s tech pos engine. It has to be massive to make power, because it is so ancient and inefficient.

12.1 compression so way too high to boost and besides an 8-71 is way too small for a 632. With a forged bottom end, that compression, and cam it would love nitrous. Not a 500 shot because I don't think you would want to spray 50% of the engine's power built like this in nitrous alone. 200 or 300hp in a couple stages or ramped in progressively sure.

I’ve even used a mothball before because they used to be made out of solid methanol. 50/50 Ethel and AVgas and hang on for dear life.

Sadly, he didn't live long enough to see it happen as he died in 2010.

I take it you're not talking about a GR Yaris? So that is like saying "hahaha my car engine is bigger and has more power, then my sister's moped." And even if it was a GR Yaris last time I checked it was a 3 banger, which kinda says a lot. Not to mention the 2JZ GET which is a straight 6 that can put out about 2,000+ hp. 1,000 hp sounds like a good platform. But it depends if they mean 1,000 potential hp, or 1,000 hp out of the crate? If it is out of the crate then yes it is a really good base to start from. If not then you still need a lot of work to do and it doesn't seem as great anymore.

1 There is nothing modern about forced induction, mercedes has been factory supercharging cars since the 1920s. 2 The heads actually are extremely efficient which is why the thing is making over 1K at only 6600 RPM. Just one of those aluminum heads cost more than most people pay for a whole used car. 3 More power from lower revs is always more efficient than a stressful delayed high RPM peak. 4 The thing would run even better with a carburetor as proven by Engine Masters carb vs efi dyno shootout.

[@damniambad]

@@Impactjunky This tech have been used even longer than merc has superchargerd their engines. So this is more like how can we make the most low tech engine using best manufacturing technics in use today. Figures speak for them selves. Less than 100 bhp/per liter just screams a question of how much does it make when supercharged. And that's probably what happens for the most of these engines anyway. And two valves per cylinder aren't that much of a restriction with forced induction. My very very important and appreciated opinion here: Ford 1liter three cylinder turbo engine is more of an pinnicle of modern engineering than this. It actually makes that 100bhp/liter. Ten of those even weight less than 632. This is just "Let's take a truck engine and see how much can we cuddle out of it. By supersizeing it.". Now I'm not saying this isn't impressive. But this sure is not the best Cheavy can do with an engineer or two.

[@Impactjunky]

​@@damniambad Nope, the big block Chevy hit the market in 58, long after the first supercharged cars of the 20's. There is almost nothing modern about the manufacture or design of this ZZ632 either. High flow aluminum heads were available in the 60's and people have been home building 632 Chevy's with and without aluminum heads and fuel injection for decades. Comparing the power per liter of a forced induction motor to a NA motor is like comparing apples to oranges so your comparison with that weak little three cylinder makes no sense. Also the word is pinnacle not pinnicle.

[@damniambad]

@@Impactjunky Oh you are right! It is spelled pinnacle. Other wise we can of course make whole new segment for zz632 so it can actually be good at something else than being big. Like the most american thing ever -segment. Or just best v8. Of this year. Made in america. And Is over 6,2 liters but under 12. And makes lot of noise. But not compared to displacement, cause its just too big for that.

[@annieworroll4373]

Considering the time and expense involved in modifying an existing engine to put out this sort of power, that price, while more than my entire car was new, that pricing really isn't all that ridiculous.

[@sethmaki1333]

Well, I once saw a 87 Fiero that someone somehow shoehorned a Mk VI 502 crate motor into, complete with Hilborn style injector stacks. There's a pretty good project idea for Zach.

I’d love to put this into my Pontiac 6000 LE.

[@wdefghjuefhdegtfthtgf1351]

In marine applications big blocks are still common including more then one the 454 is still in thousands of boats. As gm makes many of murcrusers engines from 4cylinder to big bad v8s. And there are some nasty race motors

[@cliffordbradford8910]

Tru dat but at this level of power/weight/cost I'd go for a helicopter gas turbine. 😁

[@aye_its_sparky7164]

if i knew how, i would love to cram one of these in a 76' comaro. might have to completely rearrange the frame work, but it'd be cool.

The 454 big block continued well after the 70’s with the final variant (vortec 8100) used all the way until 2001

[@justanotherdmax]

2001 gmc sierra 2500 3500 had a 502bbc (8.1L) with an allison or 6r80. Some suburbans had the same setup. The 454 was 7.4L

[@kumaWRX]

@@justanotherdmax just guessing but I believe he meant the 8.1 was the last factory engine of 454 architecture. Also, small correction, the 8.1 was 496cid.

[@joshbumbar3895]

K5 Blazer was that big block would be fantastic that's one of my dream builds

[@Mikey-wf9py]

The last big block was actually an 8.1 L vortec and it was in the 2500 HDs and bigger from I believe 99 to 2006 but I could be incorrect on that and they also make a vortec 8000 8 L which is still used in marine and commercial industry settings and they also still use the vortex 7400 which is a 4554 and industrial settings as well

You can drop it in my '63 Chevy pick up! It would fit nice and neat under the hood with probably no modifications to the hood. I would also like to hear this bad boy running!

[@BlueCollarExCalifornian]

This thing would be perfect for a Chevrolet Cheyenne series pickup restomod! I can only imagine dropping one in a 1989 GMC 3/4 ton single cab longbed 4x4 and using it as mountain tow rig.

I’d dump this in my slammed 89 OBS dually and ditch that tired 454 .

Now to snag those engine mount dimensions so I can start prepping the Del Sol

[@danielperez6369]

You should keep it classic/classy put it in a chevy nova II Great aftermarket support and guys have been putting big blocks in them for years. The weight to power ratio would be off the charts.

I have been trying to find a measurement sheet that details widths between mounts, height from the top of the throttle body to the bottom of the oil pan, width left to right, length from water pump to flywheel and anything else that I can get my hands on. All I have is small blocks but want to make the jump. This beast is one helluva jump!

[@iowaox]

A hilarious use of that engine would be to throw it in the back of a compact like a chevy spark and turn it into a rear engine fwd car. would take excessive amounts of modification and would probably tear itself apart but would be great to see.

Here's two ideas for that motor: Easy: Make a new version of Stubby Bob. Instant cLiCkBaIt, or whatever. Hard: Make a Chevrolet version of the Dodge Tomahawk.

[@dieseldabz7104]

Like a 2022 GMC Typhoon!

[@jsomething2]

on youtube there's a old power block TV show uploaded that they took a old body style like the mid 90a ss454 truck, and made it awd with newer tahoe parts. they did a cheap ls swap, but this engine in the 2 door /blazer/Tahoe of the same Gen would be a full sized typhoon with the newer awd would be cool.

[@paddle_shift]

Minor gripe: big block did not go back to the 50s. I have the original Hot Rod magazine from 1965 debuting the "Mark IV mystery motor" which was the 396 in the passanger cars and the 427 in Nascar. Junior Johnson made the mystery motor famous in Nascar. The "W" engine 409 was developed in 61-62.

[@ericborgen7311]

That is one cool engine I have seen various horse power ranges for the 632 V8 just think how much more powerful you could make it if it had a super charger or a turbo charger on it

[@yoelespinosa6284]

ZZ632 has 12.0:1 compression ratio..This GayM motor will blow up with little too much boost. It’d have to be fully rebuilt and stroked to low compression for boost. Other wise maybe 1300-1500ish hp with twinscrew supercharger and maybe less than 14 psi. 426 hellephant has 9.5:1 with 15psi of boost from supercharger.. can still handle far more boost with turbos with supercharger still on and make lot more than this high compression GM motor. Even if they stroke the ZZ632 to low compression and run turbos maybe they’ll make near 1600-1800 but hellephant can make that easily.

[@Boatfisherz1]

I love these videos!! So good at explaining car engineering.

[@justincoots6261]

632ci equates ti 10.356 liters, and manufacturers always round up, so they’d likely advertise as a 10.4L. Just like Ford’s Coyote engine actually has a displacement of 4.951 or something like that, so they round up to 5.0 and not 4.9. Small correction is all.

[@dontyouworryaboutit_]

The 3rd Gen coyote is over 5L now it’s closer to 5.1

[@Heyitsallgoodman]

No that rounding up was for the Windsor. They haven't don't that since 1994. But yes that is true

[@AbzAden]

Same with 6.2 L V8 Amg engines

[@electricfeel9501]

ok?

[@justincoots6261]

@@dontyouworryaboutit_ it is over 5 liters but it would still be rounded to 5.0. It’s 5.035, closer to 5.0 than 5.1 so round down
