Building GM's most powerful Engine Ever, the 650hp LT4 V8!

Come follow us along as we tour the GM Engine Plant in Tonawanda, NY where they build the 650hp LT4 V8 and many other engines.
Note: the crankshafts shown during the machining process are for the 5.3L EcoTec3 V-8 truck engine, not the LT4.

I toured the engine plant my Senior year of high school 1972. It was amazing. I'd like to see it up close once again.

[@stanleymasterson1135]

You're really aiming high...

[@TrojanLube69]

This would be my favorite type of willy wonka experience.

[@phattvids]

Glad to see a fair amount of emphasis put on the human fact of the facility. As a new hire at GM's Wentzville Assembly,and former 14 yr. employee of Dodge/Chrysler,what the Plant Manager says is true. Without the people,the machine which is the plant,doesn't function. From the highly skilled tradesmen & women that keep the machinery and tooling maintained,to the lines people that perform the high skill,delicate assembly processes. These are all top notch folks. Very proud moment for me watching this. UAW for life,Union for life.

No..stay away from the union..the only thing you get from that is an "O"nion. You can be replaced at any time.

[@michaelbates2035]

I am with Brother I am a retired GM use worker

[@fredericrike5974]

@EpiDemic117 Gm's and Ford and Chrysler want to build 4000#, 650 hp cars and 6500# trucks for $45K and up- they make more money per vehicle, and their costs are only slightly higher than the small car's. We have consistently failed at the production of small well built cars. Some individuals have designed and built some here but Detroit seems to be unable to do so; the success of the Ford Mustang is as much a hail Mary pass to save Fomoco from financial ruin from the Edsel followed by the Falcon failure to start. All this because "Americans don't really like small cars" was their mantra; now the quality small cars produced by foreign owned plants with American help out number the American cars- Toyota is the largest car builder in America today. The Big Three seem hopelessly unable to "get the memo", so they are going to get out of the small car and passenger cars altogether- except maybe Cadillac and Corvette- and oddly enough, both are client plants of Tonawandas!

[@richa9719]

I appreciate all you do to help build engines. You union bosses are helping eliminate your jobs. Hopefully you guys figure that out before the engineers automate what you do and no longer need any humans.

[@689452379]

GM stuck with the pushrod engine and did so brilliantly. These engines are bullet proof. They took the original small block and perfected it. Yes, I'm a Chevy guy.

[@sancharino6878]

Yep

[@Scubasteve22]

Can't really argue with success.

[@wyattoutlaw2370]

What ? So they never went to overhead cams ? I guess they already have bucketloads of power without needing to go overhead cams.

[@sandyrandall7341]

Overhead Cams require too many moving parts and way too much to create an easy engine to manufacture and to maintain. These engines are so easily modified, 1 Cam 1 Chain I really don't see the reason for a dual sprocket Drive with 2 Cams per head. A Cam swap for performance would be ridiculous!

[@Hot80s]

old school 2 valve per cyl why fuck with perfection.

[@rondail5675]

My GrandSport is running great! Thanks for doing good quality work assembling these engines. It's important to us owners.

[@ramairgto72]

The valve retainer install blew my mind, anyone thats every struggled to get them on (and off) this was almost magic. Great video, think I would be asking Steve what I needed to do to get one of them out the "back door". Thanks for the upload, very well done.

[@coreyfrasnelly7364]

ramairgto72 lol almost like alien technology no flat head screwdriver

[@richardkautz2947]

I became a Chevy man on my own. Growing up in a a Ford household didn't keep me from seeing for myself the things that Chevy "allowed" the common man to have and build his own performance machine with parts interchangeability and ease of maintenance. Simple, easy and reliability are the keys to customer loyalty.

[@mewrongwayKOCXF]

I also grew up in a Ford household! Got tired of walking to school and the grocery store! Bought a Chevy and went out on a drunkin Ford killin spree! Ah those were the days!

[@Nameless_rat]

Wish I could work at that plant, seems awesome.

[@stevematz7354]

All these Tonawanda Built LS V8 Engines (i.e. LS3,LS1,LT4) have probably more precision and accuracy than you could ever obtain even in an old School Clean Room Race Shop. Probably the reason the LS3 crate engine is the most popular engine for Hot Rod and Resto Mod Builders. Just going by today's Machine Shop Prices; you could not even get close to the cost of a built Crate engine which as you can see by the Video is blueprinted beyond any normal type Mfgering/ Assembly. With the technology of today's Computerized Robot controlled Machinery (i.e. CNC's,lasers, Mills,Boring/Honing,Broachs,etc. They can build an engine with a precision pretty much unobtainable in the days of production Muscle Car Engines of the 60's and early 70's. Probably why Chevrolet has so much Confidence in their new ZL1 Camaro, that they will let you go Off Road Racing and still maintain your full warranty. Don't remember them doing that back in the L88 / ZL1 Days ... Great informative Video !

[@803brando]

+steve matz yeah a properly built early small block or big block on a budget is about $8000-$10,000. that LT4 is $12,000. GM is making the choice easier every year. the LS9 a few years ago was out of most people's budget @ $22,000. GM is finally coming around and thinking right.

[@gmansplit]

[@jeremybettis8446]

Could you imagine if the engine builders in the 60's during the hay day of muscle cars could see this stuff, what they would be thinking.

[@tedbear8168]

I think about that every single day..

[@charles-y2z6c]

Thank you, I have driven through Tonawanda 100’s of times driving from Rochester to Buffalo, never knew this.

[@edwinstorz702]

Absolutely mind blowing, especially when a Machinist like me from the old days of hand setting dials to read Thousands and now 40 yrs later we are talking Microns, POW TO THE MOON!!! Thank for the mind trip, lol.

[@jlo13800]

I dig the big block 2 stroke conversions. I good motor to start with is a Harley v-twin 1600, S@S billet aluminum, or honda 1800, kawasaki v-twin have room to cut any port pattern nto those huge jugs.

[@leesantos9711]

Glad GM still building these reliable beasts !

[@MarkCalica]

I hate it when snobs out there think that american engines are less techy. In fact its not.. it's a simple engine design and if it ain't broke, why fix it?...

[@MrSotenacious]

Exactly every modern engine design has its pluses and minuses no design is better than another.

[@rowanw1131]

yep nothing dumb about it. But the STUPID power it makes :)

[@joshkiej6601]

+Chris A so you are saying a rotary (wankel) is better since its the simplest engine there is

[@jdrok5026]

The Real Santa Claus well technically it could be if it had a bbc in its place but the pushrod block is actually complex

[@stevematz7354]

And look at it this way; Back in the day if you got 100,000 miles out of your engine before needing say a rear main seal, valve job, etc. you were doing pretty good. Now days 100 grand on these engines is trivial. This because the precision tolerances that old school engines never had is incorporated. These Engines even on critical clearances like Con Rod big end Housing ID and Block main bearing clearance ID will stay within .0001 (that's 1 ten thousandth) accuracy. I can remember brandnew Gen 1 SB LT1 Cranks being out as much .008-.010 on stroke from front to back. You won't see that on an LS Crank, another reason these engines have double even triple the longevity of GEN 1 Engines ...

[@troypower4733]

Great video, very informative, really appreciate the insight into a top notch plant producing a top competing performance engine that has great racing heritage and a performing pedigree including many wins over Europe's best sport cars at a very competitive price. The LT4 is a marvelous reflection of engineering and production competence, this plant deserves a big thumbs up! The Tonawanda team is certainly performing at a top level. As for the negative and very misinformed junk comments from some of the haters below relating uniforms to professionalism, a clear demonstration of insecrinty and their realization of how far behind they have fallen behind. Thanks to the team for a great job, I recently took delivery of my 2015 Z06 and could not be happier!

[@masskhamisi4]

That is a badd ass engine building plant..reapect to gm for keeping the original pushrod engine alive

[@mewrongwayKOCXF]

And Kicking Coyote ass to the curb!

[@laloherrera5173]

I was honestly more interested in all the robots and technology around the plant throughout its assembly/production lines the the actual engines. Im an engineering student but i also am studying automotive technology as a hobby.

[@joshua805450]

"highly skilled line worker" 😂 funniest part

[@efsyoo]

We have some of those at FCA in Detroit.

[@stanleymasterson1135]

When that worker was asked what his job is, he replied, "I screw things"

[@remowilliams623]

They built the famous LS6 454/450 horse in the 70"s, Which you can easily make it produce more than 650 HP, without a Supercharger. Always loved Tonawanda, keep em coming Guys and Gals.

[@drummer2fear]

I live 500 yards from the Tonawanda gm powertrain. You can hear them testing engines. They run them full bore for looong periods of time. Its awesome.

[@joemilko2589]

GM used to put a sticker on the valve cover that said "Power by Tonawanda"

[@FentonDaniel]

Love love love it! I think there is a gap in the market between standard "car porn" and technical informative videos on KZbin. Much like the install videos and even how to check tire temperatures videos you guys are doing is going in the right direction. Much like motoiq provides that in prose, speed academy is in video format. Keep at it!

[@Carnutzjoe]

I'm surprised they don't do a test run. As the top engine I would expect each LT4 would be tested and even put on a dynamometer to document performance.

[@TrojanLube69]

Machining is so precise that is not necessary. Only the test sample and up to the final engineer prototype production ready assembly one.

[@goyeabuddy]

very impressive! it looks like a nice place to work.

[@jarin12ga]

They should hardly call this motor hand built??? LOL

[@justsumguy2u]

Some of the most serious musclecar engines GM has ever made came out of Tonawanda.

[@panagiotisf7228]

can one of these workers ecplain to me the camshaft lifter issues we have with the l86 6.2

[@johnrunion7258]

Didn't notice deck plates torqued on durning machining.Touquing head bolts and 6bolt mains distorts the block by microns.This is a high level mass production process nonetheless.

[@steeplecab]

I can't help but miss that Tonawanda Orange that Chevy engines used to be painted.

I'd love to see a tour of where the blocks are cast

[@idahorx1]

There was a casting plant in St. Catherines, I toured it many, many years ago. Wonder if that plant is still around. I worked down the road from Tonawanda at Harrison Radiator.

[@UndergroundTrev]

GM really needs to stop re-using the LT designation. This is the third time, it's just getting confusing now. Great video though! Very interesting to watch.

[@Spahi77]

I am thinking the LT4s of the mid 90's...has me confused....if someone with knowhow can chime in would be great

[@UndergroundTrev]

+Spahi77 the LT engine designation was used on first generation small blocks (ex. 70s Corvette), second generation small blocks (ex the LT4 you mentioned), and is now being used a third time for the new engines in the new Corvette and Camaro.

[@Spahi77]

+UndergroundTrev thnx, appreciate timely response

[@jdrok5026]

yeah but how many times have they used ls? like 19 different fucking times

[@Ieatpeople2]

LS engines were first introduced in 1997 (LS1, duh), and were made every year until 2014. Thats 17 consecutive yrs using the same name and design. the difference between gen3 and gen4 motors is basically just 1 piece, the crank trigger wheel. All the other parts are interchangeable. This makes them very easy to modify and maintain. The LT designation was used in the 70's on gen1 smallblocks, then again 20 yrs later in the 90's on gen2 smallblocks, and now again 20yrs later on the gen5 smallblock. The gen1 and 2 engines share very few parts, and the gen5 shares parts with nothing. See why people complain about LT's?

[@trevordantzler5781]

71 MILLION ENGINES!!! What other single-engine plant can claim such a feat!

[@AlBaNiAnGaNgStA93]

I don't think this is the most powerful engine gm has. LSX 454R is 770 hp naturally aspirated

[@speedacademy]

Production engine. LSX 454 is a crate motor so it doesnt count according to GM.

[@joshuafinley644]

So awesome. This is one of the coolest engine building videos I've seen so far and actually seeing the engines being built is just amazing. Imagine if 3D printing becomes mainstream, I'll have no doubt that this plant will convert to additive manufacturing and actually 3D print their engines

[@MrJdsenior]

It's got a CAST crank. I was impressed up to that point.

[@Thelastoftheog]

Its a 1538mv forged. A step up from the 1058 forged lsa crank. Besides there has been less then 5 reported failures of any 4.8 5.3 6.0 cast crank on hundreds of 1000 plus h.p. builds lol

[@MrJdsenior]

@@Thelastoftheog Yeah, five REPORTED failures. Forged is the ONLY thing I would put in an engine like that. Good to hear it is. And the numbers mean NOTHING to me, sorry. Any idea how many of those 1000 Hp plus builds broke a crank, quite a few, I'll wager. Maybe the cast cranks are better than they used to be in the 70's. Maybe they are pressure cast now, or x-rayed or magnafluxed for quality, or something of that nature? You KNOW people are gonna start throwing nitrous and bigger superchargers at the thing, and that WILL break cranks, especially if they are clueless.

[@Demonbfg]

Nice Video,My little Cosworth Vega motor was made there.

[@mikeriolo7734]

I have a corvette a cts and 1500 express van the engines are amazing

[@aky19832001]

This car was intentionally designed with certain engineering flaws that are meant to fail. You can't have a reliable car that ran well all the time. Otherwise Chevy would be out of business. To bad it cost an obscene amount just to change the heat/AC diverter doors, remove top half of engine to access firewall, then remove the several hundred pound dashboard as a unit...$5000 to $6000 to replace less than $200 in wear-out parts. Oil pressure sender fail? They DO! and its a $12 part that takes $1,400 in labor to access.

[@blackbirdxx928]

5 to 6 k in labor? @ a hundred an hour shop rate....50 to 60 hrs? I call bullshit. Ya, GM is going to make a part so difficult to replace, knowing that they have to reimburse the dealership if it fails under warranty...retired gm service tech in 95...I loved warranty work, especially at the cad store...sts needs a motor, warranty pays 18hrs... drop it off at 8 am and pick it up at 5:30...evaparator cores bin c/h body cars...1 he and 15 min. Warranty pays 7.2- 7.4 hrs. Shit it all easy.

[@MrAxes777]

Imagine how many jobs those machines took

[@naknakacknak]

They try to hide the fact that there are so few workes the plant looks empty. In the end, they praise the workers, but it's pretty hollow since the workers are there just to watch the robots. 71 million engines produced here and with the $400 million retooling, they will have increased production with just a handful of workers. This is typical and spells the end of employment for most people. Their ultimate goal is to eliminate all employees... It's happening all over the world. We will need a Universal Basic Income to survive. There will be no work and eventually the rich that can afford a Z06 will be gone and they can't sell them to homeless, unemployed people.

[@RossABQ]

Read the book, "Rivethead" by Ben Hamper.... robots are a big plus

[@williscurry6557]

Lots of camera cuts in that feed. With all the precision engineering the robots might engineer themselves out of a job. If a motor can run 500,000 miles in a corvette thats longer than the owner will live.

Wonder how many jobs those robots eliminated?

[@towertrash96]

With the invention of the car, I wonder how many carriage and saddle makers they put out of work. Either move forward or be left behind.

[@406Steven]

It eliminates the factor of human error. I trust a precisely-calibrated robot more than I trust a human to reliably build an engine correctly time-after-time over millions of engines. I've yet to see a machine show up to work hung over, to say the least...

[@jamesweber4938]

All those robots and assembly machines are designed, built, installed and maintained by people.

[@masmcg]

I wonder how many engineers it took to design it, programmers to make it do what it does, people to install it, people to maintain it. Also, how many people does it take to build that robot?

[@Lillyyyyyyyyyyyyyyyyyyyyyyy]

I wonder how many US jobs these robots have saved because automation cost the same no matter where you're located. "Y'all want robots or you want the plant to move to Mexico?"

Fuck not always. I drive fast every chance I get. I wear Levis and Adidas and Gucci...but never golf pants lol. Reality is the Z06 is $100K+ well equipped and not a lot of 20-30 yr olds have that kinda dough to spend on a car. Some do but most don't. I factory ordered my first Corvette when I was 29. It was a goal and an achievement. I set it as a reward for finishing dental school. I earned every penny paid for that car - no rich mommy n daddy handouts. I could have bought a Porsche, Audi, Benz, Jag, Lotus or BMW...but they didn't have the "soul" of a Corvette. I now proudy own a '19 Z06 and treasure every second behind the wheel. I have had many nice cars between the 2 'Vettes and I can honestly say nothing stirs my emotions like a big, powerful V8 in a low-slung Corvette! God Bless America! (and I say that as a Canadian!)

+jodiebreeze There is also Ed Welburn he is the VP of design for GM. Hope you google him.

[@TorontoDrivingVideos]

+randysengine service It does matter actually especially in the USA. There really is not that many visible black role models for black male youth and obviously there is a crisis in that community at this time.

[@Pursuit_Of_Speed]

+crxtech1 No there's a crisis in America. Black America just doesn't have the money to hide their issues like other races. We as a country need to work together to lift all people up. The more we can do to help each other, the better this country is as a whole. The more we engage in civil war, the weaker we are as a country. You want America to be strong as a whole? Well you must make it strong as a unit. ALL people must be strong. Not just a select few.

No clamps on the cylinders(to simulate having a head torqued down) when bored? That's one way to get oval bores...

[@jdrok5026]

ThePucko most bores arent perfectly round anyways

[@shale0984]

Lol stopped watching at "cast crank" . That's all I need to know lol.

[@josephrumpsa180]

the rods and block are going to explode before that crank will ever even think of flexing.

[@Basement_crusader]

Depending on the casting techniques (vacuum environment, cooling time, heat treatments, alloys, etc.) you can have a durable crankshaft that performs within its specified operation parameters just as well as a forged one. Think about it, if you have a engine that performs with a peak power of 650 hp why do you need to forge a crankshaft that can operate safely at 2000 hp? You don't, instead you improve casting technology so that you can cast a cheaper one that operates for the same lifespan at 1000 peak hp.

[@jdrok5026]

shale0984 why casts are strong sbcs used to be all forged internals till the 350

[@percytwatwinkle3431]

The music suxxxxxxxxxx!omg can here it over the interview

[@rbjoseph25]

Good job Obama, just what our country needed..... All that to make 650hp? Here's an idea, grab a socket and a brass hammer and beat in your valve seals, put on the exhaust manifold by hand... When it's in the car. If you don't have cussing and getting pissed at some point, then you can't be proud of what you did once it's running. Oh wait, they don't get to see them run. Not to mention 90% of the people that buy those cars aren't going to use anywhere close to that much power. In two years most of them will be smoking from all the carbon built up on the valves. Do something worth doing and stop wasting our money!

[@RichardJoashTan]

AND YOU ARE A BULLSHIT BECAUSE THIS IS JUST WHAT MY COUNTRY NEEDED! AND YOU ARE ALSO A BULLSHIT BECAUSE I AM BIASED WITH THE C7 Z06! AND YOU ARE A TOTAL BULLSHIT BECAUSE THOSE WHO ARE ABOUT TO DIE AFTER BEING BANNED FROM KZbin WILL NOT BE REQUIRED TO KNOW MY NAME!

[@rbjoseph25]

Richard Joash Tan lol z06. There's your bullshit.

[@ThePodpie]

you're clueless

[@rbjoseph25]

Oh, so when I heard on the news about Obama's "Bailout plan" for Chevrolet, that didn't happen? And I'm clueless to the fact that it doesn't take $16,000,000 machines to build a reliable 650hp car, when me and thousands of people like me have been doing it for years in their own garages. Point is, it's a waste of money that could have been used somewhere where it's really needed.

[@RichardJoashTan]

Jim Miraglia AND ALSO YOU ARE A TOTAL QUASI SERIAL LIAR AND THE WORST OBAMA-BASHER IN HISTORY, DESPITE BEING A GM ENGINEER!

[@raygomez1298]

fill up your gas tank with water, put an H2O splitter in line with your injectors and let your engine run on hydrogen. It works great and has a little more horsepower than gasoline and the exhaust is water vapor.

[@nigelsenchez]

Hydrogen bomb

[@richardheyward3791]

Can a consumer go to Tonawanda and have an engine built right from the plant?

[@Redmallard]

Very nice.👍
