NEW VIDEO EVERY WEDNESDAY!
The 427/ 7.0 litre is and always will be a legend. Big block cubic inches in a light weight small block package. In my Z06 around 18 in city and 27 - 29 highway mileage. Sure, a person can add a blower and get close to the performance of the LS7. Add the same blower to an LS7 and get out of the way! I love my 2013 LS7. 3150 IBs Z06 will rock !
But then it will drop a valve or the rods will rub like my 06!
LS7 is no doubt a badass engine as long as you keep it NA. They won’t take very much boost.
Seeing all the cylinder head bolts tightened at once made me so happy. OCD was happy.
looked sloopy
James Avery right! OCD mustn’t be that serious
@@sulkmahidonkeydek3424 ocd level over 9000!
My OCD is only pleased when I do it with hand tools. 😎
I live 30 minutes away from the corvette plant. Its really cool to know that all corvettes in the world come from that one place.
that is pretty cool!
But it’s not the only plant that’s capable of assembling a corvette. GM had two other plants that could perform that task, but have yet to ever assemble one for resale.
I like the robotic tightening up all at the same time. Very cool.
pretty neat I myself am a factory worker and I like seeing things manufactured
Apparently all the posters below badmouthing OHV Pushrod Engines have never seen a Sprint Cup NASCAR Engine like Chevy's RO7 or Ford's FR9 and Toyota's TRD V8 engines. These Engines unrestricted prior to the current Fuel Injection used by NASCAR made over 850 HP using just a single 830cfm Holley 4 barrel. These engines are only 358 cu in and yet go well over 200mph even on restrictor tracks like Daytona and Talladega. The Pushrod V8 is far from being Dead ...
This is very true! What's also true is, those NASCAR engines are racing engines, and it is common to see 1-2 (or more) engines blow up at every race. They are tuned for maximum power at the cost of reliability and efficiency. And think about those NHRA big block pushrod engines putting out thousands of horsepower! Amazing! Yet those engines only go 1-2 miles before they are torn down. The LT4 and LS7 engines are production engines that must go at least 60,000 miles per the warranty, and can't be fairly compared to racing engines. There are several reasons why American manufacturers are still producing pushrod engines by the thousands: lower production cost, compact size/low deck height, simpler design, and perhaps the biggest reason is that the manufacturers don't want to waste all the R&D money they have poured into developing the pushrod engine design.
Hey genius, guess what? Push rod came out AFTER overhead cam. So basically your technology is stone age.
lol no. It's because with don't have a displacement tax like Europeans do. With have a gas guzzler tax but thats not based on displacement. Chevy gets around this with cylinder deactivation
gusgiesel most races in nascar dont have an engine blow up...
They lose engines at the same rate as every other racing series excluding drag racing. Nascar engines are famed specifically for their extreme conditions and they experience higher piston g-forces than an F1 engine due to their stroke.
And don't start on drag racing because that is a completely different story.
Where are all the boxes and bags for all the parts
Nice video. Watching this, and then watching let's say an AMG engine build, you can totally tell why those engines and cars are so much more expensive. It looks like the engineering, quality, attention to detail and sophistication is just on a different level.
Not saying that it's not really great we're able to get such performance for a low price though...
JUST ONE, ONLY ONE OF THOSE, THATS ALL I ASK FOR...
That head bolt torquing machine would make my life as a mechanic so easy. I've done so many camshafts on those ls engines on trucks. 22 ft/lbs + 90 degrees + 70 degrees and 22 ft/lbs for the smaller head bolts, if anyone was wondering :p
Hey man I've been watching you since you started youtube, your vids really helped me thanks man
It would be cool if they did a video at the factory where the LS7 heads are produced so they can explain why there have been so many head failures on all years of the C6 Z06.
+usmceric1 my guess is its to do with the supercharging if its more common in Z06. from the looks of it they retain same compression ratio boosted or not. recipe for disaster
when boost and heat is added. the heads try to lift themselves off the block. they need to be built much better for boosted engines. lower comp ratio or use E85 etc as a fuel
jack black c6 z06 wasn't supercharged. only the zr1
If GM built their cars like they built their engines, they'd be unstoppable.
Unbearable Pain what a shame nothing it's perfect
ar po 'Finally' had a turbo? GM was the first company to turbocharge a gas engine in a mass production vehicle.
@MrChad97Z the ls7 problem wasn't really on them.
It's always fascinating to see what kind of tools they use. But boy.. as a mechanic I'd die of boredom doing the same things over and over again, though I suppose some are happy with jobs that allows you to stay active, nothing wrong in that.
Great video though, such a high amount of interesting videos you have.
Same unless it was a company such as AMG. Doing the 4 cylinders would be fun along with building the twin turbo V12s for Pagani.
The tour guide said they rotated positions to keep the employees engaged.
One of my favourite videos you've uploaded
Great job Rob Nichols and team.
I'm a GTR guy but I still want a Corvette too. I LIKE IT!
These are works of art.
So are z28 ls7's revised to fix the valve guide wobble that plagued the z06 ls7? I didn't realize how big of a problem it was until I looked into it. Really thought c6 z06s were bargains until I researched that.
Ls7 is the best sounding, high revving v8 Americans ever produced.
Was the ls7. Now it's flat plane crank gt350r motor.
Lets see here, opinion and wrong. The sound is your opinion. The revving is wrong as both the Hemi and the flat plane crank gt350R motors rev higher. Even before the flat plane crank V8 the coyote engine reved higher. Not only does the Ford make more hp per liter so does the Hemi. The Hemi makes the most overall power including torque by nearly 100hp (approximately 70hp) than anything from GM. So really other than being cheap and being a large displacement the Ls7 engine really isn't that impressive. Popularity helped the engine more than its engineers.
"Flat Plane" is just marketing jargon for "It's basically two 4 bangers mounted together" .They have to use acoustic tricks both electronic and analogue in order to get it to sound great.
PyroBlonde7777 he never said highest revving. just high revving.
Jman9112 nop is the voodoo engine in the gt350 the best sounding engine
so what lubricated the engines during cold testing? assembly lube? i realize the load is not from internal combustion
Before you ask! Next Wednesday will have the explanation portion of #ProjectIntegra. Install and testing to come after, hopefully a few PI videos in October. :)
1:50 That's so satisfying to watch.
Among all the production companies, I think Porsche's the most impressive.
haha i noticed you put background music all those people getting all pissed about not having any, good job on the improvement either way
mkelebay Well, to be fair most people said they don't want it, and I don't plan on using it in the car reviews. I included it here because the background noises were a bit harsh, so I reduced them and added light music. Hopefully everyone's happy haha.
Engineering Explained haha, doesn't really matter to me, but an interesting video nonetheless, could you explain what the differences are between these two engines are, i know the lt4 is supercharged, but is it just a smaller displacement version of the ls7 pretty much? if you're busy or whatever ill just google it
Engineering Explained nice! I thought that was actually at the factory. In fact early in the video one guy seems to look up at the ceiling bewildered right when it starts to play. I thought it was some sort of bizarre paging system where you play a specific theme song for someone since it might be too loud to hear your name.
Fantastic engine! North American Muscle at it's best!
I like how many comments are engine bashing and is calling them primitive, when the most only understand very basic knowledge compaired to the ones actually making them, it's pretty stupid
Dude! This video was awesome and educational. Thank you so much for this! :D
Hi Jason, thanks for all your videos. Do you know anything about the factory fault on the LS7s with the C6 Corvette Z06? Something regarding valve guide wear, I'm not sure if it was just the exhaust or both intake and exhaust valves. The valve seat may not be a fully concentric design which results in the uneven guide wear. Chevrolet did not do a factory recall and repair is very costly so I'm hesitant of buying one. Would be great to get your opinion. Many thanks
Engineering rulz!
Very interesting, good job, thank you mate.
cool a Mobil 1 engine oil huh..nice i use that oil too..: )
I remember when I was a young engineering student many years ago and I got in a discussion with my vibration & kinematics professor, he insisted that the word was “Damper” not “Dampener”. After all these years I still have a problem when I hear someone use the word “Dampener” but I hear it often when dealing with engine builders. How did this term come about? For me the word should be Damper as in, harmonic dampers or harmonic balancers. I am a retired mechanical engineer and hobbyist engine builder so maybe I missed something along the way, help me out.
No more back Alley, Chevy engine Building. No wonder they are so Fast.
Looks just like the Caterpillar engine assembly process but on a smaller scale :p
Do a video like this for the 5.7L Hemi vs the 6.2L Hemi!
Anyone criticizing these engines have never owned one. Let alone built one.
Adding the weights for balancing, is this done on the testing station?Are the cylindrical shaped weights added to the flywheel only?Also are they welded onto it? But really great Vid, Thanks buddy
i just wanna see a eng get put together without editing video....
It was a tour where they were being talked to by the employees. If you wanted that you should pay for the tour yourself, although there would still be other noise and staff talking to you.
hey when are u going to do a review on c7 zo6? I love what u did on the c7 and cant wait to see what you have to say for the new and more powerful zo6!
the engines are built in New York (Tonawanda GM Production)and shipped to Kentucky to be placed inside the vehicle. not a bad video though.
Lol all these people comparing the GTR's twin turbo V6 to an NA LS7. I'd say to compare it to a twin turbo LS3 but the outcome wouldn't be in their favor...
Also the LS7 is more than 100lbs lighter since it's made from Aluminum.
Yea well it’s a 3.8 V6😑. There’s no comparing really
@@alldirty1370 the Ford GT is a 3l v6 and only makes 100lb ft less than the lt4
Wait a minute.... when she is bolting down the oil pan she is not crisscrossing, she's just going one way.. isn't that the wrong way? wouldn't that squeeze the bead of silicon out uneven?
+yourleftnut1
BAAAAAAHAHAHAHA
She was only running the bolts down closer. you can see a gap between the oil pan flange and the head of each bolt.
PushGOD engine.
it's me or it's the god father theme right there? 05:10
wouldn't flywheel balancing increase the torque that the crank has to withstand?
Thank you!! Awesome video!
Excellent work!
Is the lt4 related in any way to the lt1/lt4 if the early 90s vettes and camaro? Also, wasn't the ls7 in the previous gen (c6) corvette Z06(so, it's more of a hand-me-down to the Camaro)?
wouldn't cast iron be a better choice for a block and cylinders since aluminum does not have an infinite life cycle?
I would say a cast iron block would be desirable if the objective were to design an engine for maximum durability but for a high performance engine in a car such as a Corvette, I imagine the lighter weight of an aluminum block is preferred.
Cool video man
GM proof OHV/push-rod engine not die yet
And this engine is relatively old. Now GM makes high volume pushrod engines that make more HP per liter than even this engine. Although the LS7 will always be a legendary engine with it titanium connecting rods and massive output for a naturally aspirated, port fuel injected V8 that's lighter than many V6's and even some inline-4's.
Awesome overview, a little open source music between narration pauses would go a long way towards an A+
***** It does have open source music between narration pauses, it's turn down as to not be annoying. :)
what is the clutch in this engines,sport or normal,because i know over 300-350 hp it use sport clutch, of the another hand sport clutch is more difficult to drive on the ordinary road.
great engine for v8 motorcycle
so if i understand correcctly, both these engines are the same except the lt4 has a super charger and different exhaust?
HateCrewReaper Nope, different blocks completely. They're just currently the two highest performance engines going into Chevy vehicles. LS7 is a 7.0L, LT4 is a 6.2L.
Awesome job you guys have there .. z06 is also my favorite car and nice job you do keep it up :-)
LS4 with a intergrated intercooler for the supercharger. I didn't know that was an option for the ZO6. Know wonder they beat the Hellcat.There both incredible cars for the money. The best is buying a 3 yr old ZO6 and saving 30K
That’s the LT4 engine in the C7 Z06 and Cadillac CTS-V (gen III) with the supercharger, although the LS9 in the C6 ZR1 also has intercoolers in the cover of the supercharger.
Great video!
Why did they put the plaque on the side of the engine (07:03; difficult to see) ?
They should put it in the top-center of the engine (like AMG or Bentley).
awesome video, thank you :)
How long does it take one of these assemblers to build an engine?
IM sure someone said it ,but the LS7 is the C6 Z06 engine not the Z28 engine. The Z28 had a Ls1.
Kame House Cosplay - The LS7 was also standard for 2014 & 2015 model year Z28 Camaro's. The last time an LS1 was used in a Camaro was in the 4th Generation ending in 2002 model year production.
Good luck on those spark plug changes...
So, are these motors built in Kentucky for the same reason the 787 is built in South Carolina? Not for quality, but for cost....?
WE WANT MOAR INTEGRA! Or at least your Subaru! JDM
Chaz Gunther I know! I'm like a mother without milk. I'm trying really hard to work on it this weekend.
Tri-y headers, hmm... So my 1991 Camaro with SLP Tri-y's ARE desirable? Nah, just space saving :rolleyes:
Thanks for the great video. Always a pleasure! I'll be sharing this often.
Cool video!
Cylinder head -"Not a cheap item, right there.." - Is it only 2 valves per cylinder?! "Rockers"?
How much power can the ls7 block support? Who re-sleeves the LS7 block for Gm?
how long does it take for the engine assembly per unit?
Great video.....
If the new generation alpha platform Camaro has a LT1 engine what makes that engine so different from the current LS engine in the 2015 LZ1 Camaro? Same 6.2L size but obviously the two engines have non similar parts? What are they? Thanks.
Whole different block and parts
What is the required certificate for this job?
Thank you!!
Do they break these engines in on the dyno before Install?
Simple question but why don't you car manufacturers install TRUE headers in these high performance machines in the factory IF the buyer wants them? Just charge for this option accordingly all the while making installation much simpler?
I believe this has to do with emission regulations and costs. Its cheaper and easier to get these motors to pass smog with these "exhaust manifolds" than headers. American car manufacturers have always been a bit cheap (I'm american, I like the cars, its just a fact. Don't hate). Don't quote me though, I may be wrong.
( 07 Vw GLi 2.0t FSi) i got a code that says boost pressure lost from turbocharger check d.v. Then i put a New divert valve and a new Intercooler and im still losing boost. Can it be the PCV valve ? when Engine is running and i remove the oil cap the engine shakes and acts as if it whats to turn off. ? Thank You Engineering Explained
Great vid
What's the specific job title for this?
Mid engine C8 with a 6.7 litre LT5 and a LS8.
Questions asked at 6:38
"What bolt requires the most torque on the engine?"
"How would one torque it down without the machine you use here?"
+JDMricist not sure about the first question but the answer to the sec question is a torque wrench to the specified torque.
+JDMricist as for the 1st question im guessing the crank bolts
+JDMricist You would use a Crank Bolt Removal tool, its almost like a long wrench and at the end are two bolt holes to secure to the crankshaft, then at the end of the crankshaft you use your ratchet and socket to loosen or tighten the bolt. So the crank bolt tool is used to keep the crankshaft from turning when you loosen the bolt with a ratchet
How do they integrate the inter cooler within the supercharger?
nice vid man! what's up with that weird ice cream truck music though?? xD
Sameep Sheth I was hungry, it was warm.
Why is the oil added by weight? Thanks.
Ammount of matter is not it's volume , but it's mass . Liquid can expand , but mass remains the same . More accurate way to measure .
Thanks.
In a mfg. environment I would say it's easier to dispense by weight than it is to dispense by volume.
Mladen Milić
Why didn't they keep oil in the refrigerator ?
It would be more convenient than weighting the engine.
I do not work in GM so I have not idea .
Differences/advantages of a 7.x L v8 vs a 7.x L v6 vs a 7.x L v10? Really just engines with the same or close cc but different amount of cylinders. Would be a cool video sorry if I didn't explain the question to well
Odds are that a 7.x L V6 would be too big for its own good, and not make enough power versus the weight it is. As for the V10, just for reference I think the SRT Viper V10 is an 8.8 L (Dont quote me on that), soo having a < 7 L V10 would be interesting to say the least.
Kingdom Of Mog I have quite a few videos on this sort of topic, check out the various engine designs towards the end of this playlist: ua-cam.com/play/PL30C950600B683799.html
Big Mike
Lotus Esprit V8 had 3,5L turbo V8, 350bhp @ 6500rpm. Actually it was capable of 500bhp, but tranny was far too weak, so they removed intercooler.
Right. But that in reverse I'm thinking is a bad Idea. I know Ferrari has made 12 cyls with under 4Ls. I'm talking about making an engine too big for It's own good
If you keep bore/stroke ratio the same, v10 should make more power due to better hi-rev cylyder ventilation, but v6 will have slightly better gas mileage.
Will this fit in my Honda civic?
some reason i can't thumbs-up your comment on #projectintegra , engineeringexplained. maybe let that happen so you don't get 9001 questions lolol~
Quick question, the mass of the engine is measured in pounds?
Prateek badiger Weight, yes.
I thought the performance build center was in Pontiac Michigan?
+Jon Car It was at a different location initially I believe, but this is where it's currently located.
+jvp Video Productions That makes more sense to have them next to the plant at Bowling Green. Would save on transport costs
+jvp Video Productions Is that the same Tonawanda plant that made the Corvette engines back in the 60s & 70s? Our 1975 Stingray is coded as a Tonawanda engine.
Was Wixom, MI.
I don't care where it is that's BAD ASS!!!
I hope new LS7 they make new material for valve guide.not like my LS7 in c6 z06.
Camaro vs mustang which ones faster and/or better. ?
Straight line performance - Mustang
Track - Camaro
They cold test the engine before filling it with oil?
It has some oil in it, just not all of it.
I've seen BMW do something similar with the motors for the Z4. I understood it as making it easier to detect issues without the noise of combusting fuel and a lower chance of a really bad setup causing damage, but it looked like they worked a lot of poke-yoke into that LT4 build. Does the cold run simply give more precise feedback?
carlsojos
I think the engineer in the video mentioned dry run checks for leaks and uneven sealing. When they are found, they get fixed before running with gasoline which can destroy an imperfect engine.
Engine is not fill with Break in oil, Royal Purple, Amsoil or Lucas oil additive.
you don't need zinc for modern stuff like you use to with the old
new engines don't need broken in anymore, if that's what you mean
***** old ones that especially use flat tappet stuff needs it to protect the camshaft from damage...
There still are modern engines with these!
Outlaw That's what the people who sell that additive say.
***** that's just your opinion nothing more...
What is your career title? I want to study engineering but the one that specifies in cars! and as ive seen your videos, you are in that. is this mechanical engineering?
Gerardo Ramos I studied mechanical engineering, yes. But you don't simply study cars. You study the math and physics behind moving objects at a very detailed level.
if you want to get a job at a car company, do some extracurricular stuff that shows your interest in the automotive side of things. Like here at the University of Minnesota there is a group that designs and builds a formula SAE car. This will help distinguish you from the other mechanical engineers. Also, electrical and aerospace people can just as likely get jobs at car companies too.
The 1st and 2nd year engineering students study very similar subject matters, like calculus, differential equations, physics, static and dynamic mechanics, strength of material, thermal, fluid mechanics, etc. Each engineering specialty begins to teach its specialized fundamentals starting in the 2nd year. It get tougher from then on. You get the most drop out after the 1st and 2nd year. After that, most should be able to graduate.
Like Ryan said, get involved with the various engineering projects on campus. It gets you exposed to working in teams and you get the opportunity to network with professional engineers in the industry. Many students get internships from the strength of their school's formula SAE car.
I'm majoring in automotive engineering and I think that's what you are looking for.
What is the background music starting @ 0:54 please?
What is the purpose of those almost rectangle holes in the block at 3:30?
+Laurynas Dvareckas Lifter trays. The lifters are at the bottom. Push rods come down through there after the head is on.
I once saw someone put a z06 into 1990's (94? 95?) Grand Cherokee.
So other than the engine assesories and slightly different heads the LT and LS7 are the same engine?
+Robert Polkamp lS7 is a Gen v4, and LT engines are Gen 5. So although they look the same, different generation.
Not at all. Totally different.
Totally different but closely related, I'm seriously confused now.
Also, the Gen V LT engines have direct injection vs port fuel injection of the Gen IV LS engines.
good stuff, update on the project car?
Reference the first comment! :) (Next Wednesday, hopefully 2-3 videos in October).
Does anyone know who sleeves this block for gm?
