The time has come to finally see how much power Zac's 9.3 Liter (572ci) Big Block Chevy motor is making. We hit the dyno room at Smeding performance to get a lesson in how to properly break in a new engine and get it tuned from proper drive-ability and maximum performance.

I'm already looking forward to the new episode

Stoner 420 13 kun oldin

U should give me the old 454 sk I can use it in my camaro 😁

bigghoss762 13 kun oldin

It's funny because it still looks small in a square body engine bay.

Donovan McLaughlin 13 kun oldin

9.3 on the chop haha

Marcos Fierros 15 kun oldin

The longest lasting motors I had were all beat on daily with proper maintenance.

ThemTXHallBoys 15 kun oldin

Would you DORKY MAMA's boys PLEASE quit calling big cubic inch motors by the LITER?? That's the ultimate feminization of such a MANLY BALLSY BEAST of an engine. IT's a goddamn 565....(mathematically a 567.521...dorks...) Love y'all....;)

Donald White 16 kun oldin

Chop rate: 10/10

Smokey Yunick 16 kun oldin

It should be making over 900HP N/A, that’s one of the worst sounding motors I’ve ever heard I think you got your timing way too fked 40 degrees of timing is way too much

Dylan Troutman 17 kun oldin

Can you max hp a 6.0 L Vortec next please?

Ragnarok 17 kun oldin

Awsome, but why in gods name are you guys using cork gaskets on the valve covers? Cork belongs to the 60`s

Beefalo Bart 18 kun oldin

Whats with that 3200-4500 torque dip, that is no bueno. For a 4x4 if its being used offroad then you want your smooth power at lower RPM and the high RPM is a bit worthless. Who cares what its like at 5k RPM if it never gets used.

bo duke 19 kun oldin

Were the big engines out of stock when you were shopping? I'm concerned that you're gonna be underpowered if you ever need to change the rotation of a planet. Hopefully it'll work out for you. If not can always go all Cletus and remove the hood and bolt a blower on.

j 19 kun oldin

lmao 572 cubic inch

Adam Guerra 19 kun oldin

Lol when said I can’t wait to see what he does with it then afterwards shows a car flying off a ramp messing the shit up😂😂💯

Marc Schotborg 19 kun oldin

Chop sounds like a Harley

Chevy Alvarez 19 kun oldin

He said " bearings domt need break in....17 seconds later bearings not fully broke in yet" 🤦‍♂️🤦‍♂️🤦‍♂️🤦‍♂️🤷‍♂️🤷‍♂️🤷‍♂️🤷‍♂️

Steve Lynch 20 kun oldin

I'm going to ask a silly question, I've seen it on other dyno's, you can see your pushing the throttle but at about 3000 rpm it backs off a bit before it starts to rev, Why??

Tyler Coates 19 kun oldin

that's the dyno loading up the actual thing putting the load on the engine. it takes a second. It's also why you can see the power and torque numbers change dramatically when the test begins vs the full load.

Brandon Weller 20 kun oldin

I rate this chop 10/10 moon landings per baseball game 🇺🇸

cvo125 20 kun oldin

I know if you have to ask, you can't afford it. But, what does something like this cost to build?

HrdcoreNinja Ken-doll 21 kun oldin

That dude is the truth. We never baby a gas or steam turbine because we just changed out the bearings, And they’re Babbitt bearings. If it’s going to fuck up it’s going to do it from jump street

Montero 21 kun oldin

Will it pass smog ?

Jerry King 21 kun oldin

Why does the RPM sounds like it is "stepping"?

Rigged Tv 21 kun oldin

Wonder if smeding diesel and this company are connected

Christopher Olson 21 kun oldin

I hope you find more power out of that motor..... my 496 was pushin much higher numbers naturally asperated.

Ethan Zelaya 21 kun oldin

Cant wait to see this thing rip

Keith Waggoner 21 kun oldin

That chop gave me a woodie!!! 9.4!

Harry Moon 21 kun oldin

This what nice healthy chops noises sound like I’m going to be brutally honest with you on rating I rate this 7 out 10 just because there bigger crazier Chopy boisout there

Super Liegebeest 21 kun oldin

It will never be a fast car, the amount of gas u need to haul will slow u down.

Thomas Joseph 21 kun oldin

"I don't believe in breaking anything in"..... . . . . minutes later shows an actual graph of piston rings breaking in with HP increases.... Seriously? Get yourself educated on what "engine break in" is before you make a video. en.wikipedia.org/wiki/Break-in_(mechanical_run-in)#:~:text=The%20goal%20of%20modern%20engine,roughness%20to%20help%20oil%20adhesion.

What octane fuel are they running?

Princeps Regem 22 kun oldin

Twin charge that monster.

Colton Grundy 22 kun oldin

As I'm watching this, I can't help but think 🤔 Honda kids : WhAt Is ToRqUe 😵 HoW dO I GeT tOrQuE 😵 😂😂😂😂😂😂 There's no replacement for displacement kids.

PLK 22 kun oldin

Would be cool if it put out 572hp

Bro Tang 22 kun oldin

Forgot to mention the one thing that you are actually " wearing in " during the first few heat cycles and that's the rings.....ya mentioned it later on but not when talking about engine run in.

John K 22 kun oldin

Is he saying "pools"?

You could have just bought a Blueprint 572 with about the same TQ and HP and a 50,000 mile warranty.....

Jerry Garcia 23 kun oldin

Perfect 10 on the chop

Drake Roten 23 kun oldin

“Wow engine, you’re magic! Thats so much torque!” “Correct. Now, for my next trick, turn your attention to the gas tank...”😂

Dan Letter 23 kun oldin

Bet if y’all had put some hair around that you’d never have problems getting it in

downhillskier7 23 kun oldin

All that space under the hood time for a supercharger, whipple, Magnuson or a pair of turbos. 😈

Erik Vences 23 kun oldin

I wish I had the money to buying a bigger engine and get more power. But I think I'm just going to get my engine rebuild with some snap-ons for some more power

cjgordon22 23 kun oldin

Nothing like 700ftlbs all day and can be run on regular gas to

SwaffyX 23 kun oldin

Those are some big bald eagles

troy ferguson 23 kun oldin

That chop sounds like 2 lawnmower blades super rubber banded together twisted opposite and released in a metal room fighting pencils style

Mark 23 kun oldin

Well it fit in my Miata

Haste And Fury 23 kun oldin

That mustache is horrid. Btw, you have a lot of errors going on in your shops... bummer, hoonigan jokes. Can’t even educate either, just fed us BS about what you did. Horrible channel.

Alex Alvarado 23 kun oldin

Isn’t a 572 block a 9.4 liter*

arnulford66 23 kun oldin

Thanks for sharing this big block build. That staccato idle must be heard at the end of the exhaust to fully appreciate.

john doe 23 kun oldin

Awesome boyz

Andres Rodriguez 23 kun oldin

How much for the 454

RumRunner 82 23 kun oldin

They never say the price! 10k, 20k?

6BT_ Str86 23 kun oldin

Oh it's gonna make liberals CRY!! (Chop)

Russell Baker 24 kun oldin

Yo people that know what's up, what is that handle in the dyno room that he pushes forward? At first I thought it was the throttle buts the rpm goes up after he clicks the keyboard. I thought I knew how these thing worked but now I'm so confused. Thanks

Tabor Tackett 24 kun oldin

And that is what freedom sounds like

Connor 24 kun oldin

I bet 100million chinese dongs Banks Power could make more power with a K-series

EpicBulletStudios 24 kun oldin

That displacement is almost an entire honda civic for each cylinder

Erik Capozzi 21 kun oldin

Not really...not really at all

Kristofer FC 24 kun oldin

Jesus Christ that engine is stout, I love it

Zack Cernok 24 kun oldin

8.8 on the chop

What happened to the donk project

Ahats5 24 kun oldin

I rate the chop at 6.9420/10 until I see some 4 wheel drive burnout tire slaying.

MickeyD100 24 kun oldin

I started laughing out loud with glee watching the HP and torque dials on that first pull.

D. Hernandez 24 kun oldin

How much for this glorious engine????

Akash Kumar 24 kun oldin

You just gotta love the rs 200 at the beginning

Benr.y 24 kun oldin

I’m only a 1.3L lol

Justin 24 kun oldin

9.3L gas tank is like - "OK we are all filled up- AND IT'S GONE!"

Malcom Mooney 24 kun oldin

That sack of sh its frame wouldnt support it ,nor does it have enough brakes or suspension to stop it

That engine is going to DESTROY those 1/2 ton axles...lol. I see an 8 lug 60/14 bolt swap in the near future.

Christopher Wilson 25 kun oldin

Torque Pig. 👍👍👌

fastnate 25 kun oldin

that chop...12 out of 10 go zack go!!

Guns Cars and Digits 25 kun oldin

1.28 foot pounds of torque per cubic inch, measured with a mechanical water pump installed. That's a solid no-BS figure. In terms of how that engine revs and makes power, it's comparable to modern engine efficiency in a lot of ways. The only person that doesn't like a good 730hp big block, is someone that wants a 900hp big block, and that's just hot-rodding for you.
