I love pushrod V8's! I don't care if people think it's low tech or not, it's an awesome, powerful, bulletproof motor that produces the best V8 music out there! Amazing video by the way! I've never seen a video like it before, thanks to whoever posted it!!
The animation was created directly from the production math models. The knock sensors are installed at 0:16 & 0:53. The black sensor near the oil pan rail
One word when describing the torque on LS anything. INSANE!!!!! When my wife annoys me, I torque smack her. I hope I'm not causing her brain damage. lol
You got that right. This engine is one of the best engine designs in history. The Society of Automotive engineers voted the C5 Corvette as the Best Engineered car of the 20th Century, in large part because of this remarkably ADAPTABLE engine design. Stock components strong enough to pump 600 HP, great specific fuel economy, quiet, strong, compact, lightweight are its most basic features. Cost $1.2 Billion to produce, pays for itself by powering a whole range of vehicles, Corvette to Trucks.
@Mechknight73 Valvetrain failures are very, very rare. The Honda B series engine is an example of that as it is statistically the most reliable engine ever produced and has 4 valves/cylinder. Also, It makes sense for the performance of an engine to have 4 small valves. The vast majority of the time 4 valve engines offer more torque, power and fuel efficiency when compared with 2 valve engines of the same size.
@milkman383 good call. The square intake runners are a good indication that those are LS3 heads. However the LS7 heads were had a casting like that. At the end the valve covers look like they say LS7 but that is not the correct oil pan. The LS7 has a dry sump
How can people dislike this video? It's almost like lego instructions for an engine because of the exploded piece by piece build lol, I saw this on a screen saver in a classroom for GM auto techs and thought it was a badass model
@IBM2217 But also a pushrod will normally be more fuel efficient since the revs are kept down and it makes all its power at lower revs then a sohc or dohc. Dragsters use pushrod engine for the instant power. F1,stock cars. Use dohc for the high revving engine to squeeze out as much power as possible that's why f1 can rev at 15000 rpm +
this video is very accurate. i think this one is a 04 cause the corvet up until 03 had either a 4 barrel carburetor(limited edition) or a 2 barrel TBI system
Why would you say it's not an efficient design? Actually the LS1 onward are very advanced designs that combine excellent specific fuel consumption (great mileage) with tremendous strength, high power, durability, quietness, and smoothness. They took it as far as was needed for meeting the design criteria of one horse and one foot lb per cubic inch while keeping the engine quiet and fuel economy high. Good job by the boys at GM.
It would be great if the next gen 5.5l engine used the canted chamber design that GM uses on its 60 degree v6s. Its still amazes me that the LS cylinder head design is as efficient as it is despite having inline valves. . Damn epic motor. Keep the good stuff comming GM.
You're right in that it is fast, and a torque monster. In addition to sounding great, it is in fact quite efficient and a very advanced V-8 design. Top tier engine design with a great many advanced features, along with being extremely strong, durable, economical, quiet, etc. GM spent a good deal of bucks to cure the few ills the original small block V8 had, and went well beyond that set of limits in this fine little small block. If an owner wished, he could add more goodies, but why bother
nope, in fact its the old push rod design developed a century ago. You think they'd at least have over head cams by now, which reduces the rotating mass, developed in the 80's. Vtec is variable overhead cams. Which means the cams are computer controlled for optimum valve openings at different rpm
Great video!! Its an LS3 by the way (rectangle port heads). Doesn't have to be a OHC to be a good motor!! They stick with old tech. because it work... and works very well! Gm makes the highest quality motors out there.
it has neither, it's a single pushrod cam. The reason is that it takes more power to turn 4 cams than one. A well designed pushrod cam engine will easily outperform a dual overhead cam engine.
The talented GM designers use Unigraphics (UG) to develop the complete engine. I used 3D Studio to color and animate that assembly. You can download a screensaver version just click on the link in the "About this video".
I would agree with you on that, but it's not cheaper. That OHV engine is probably more expensive to keep alive cause it's based on a 40-50 year old design. Where a new engine is designed with everything it needs off the start, the L series 350+ engines have had to go through many modifications to serve as a modern engine. Porting holes for sensors that exist at the time, saying hello to fuel injection , modernising output performance. It's really tough. Unlike ford, they held on to their pushrod
I believe he was refering to v8s in perticular, in which case he is right. Each head has an intake and an exhaust cam, seeing as how a v8 has 2 heads . . . and 2 x 2 = 4 you get the idea.
@IvanLouiseBiggin Euro engineers often forget about reliability; wring everything you can out of that design, and if it breaks, blame the driver. Before using the LS2, GM Holden built their own V8s. Loosely based on the Chevrolets of the day, but vastly improved. Lighter, more powerful for the size, and more efficient. GM's Australian division has been building them tough for a long time. They got that filter placement right the first time, why change it?
I believe you've confused the difference between 4-valve and 2-valve performance characteristics. Pushrods enable the engine to be more compact heightwise.
Its older than 30 years. They haven't made a DOHC because they haven't had the need to. The Chevy small block matches just about any other DOHC engine in its class and it makes monstrous torque.
Pushrods motors are OHV motors. They have one cam shaft. SOHC motors have 2 camshafts, DOHC motors have 4. You may call the pushrod motor "old tech". But the OHC motor is actually just as old.
@FYI1337 Fiat can't really complain about "old" technology like pushrods; part of the excitement of Italian cars is whether or not you reach your destination. FIAT is short for Fabrica Industria Automobili Turin. In Australia it's disparagingly known as Fix It Again Tony. OHC will often do no better than pushrods under extreme conditions. some European manufacturers, in an effort to squeeze everything out of them, put the valves close enough to hit pistons if the cam chain snaps. Fiat did.
the greatest thing about the ls-series engine is the aftermarket...not just the aftermarket, but the huge following that comes along with the long lived small block chevy. the sbc is probably the most popular engine in performance and motorsports ever. i have an e36 m3 with a 3.2L I6 that weighs 100lbs more than a 7.0L LS7 V8. they are light, powerful, affordable, strong, and more race proven than anything ever made. you're very limited as far as upgrades and aftermarkets go with bmw and
cadillac STS and Northstar V8. Pushrod and overhead camshafts engines been around the same time. Pushrod engines are lighter and easier to work on and repair.
the timing assembly on the OHC and especially DOHC are a nightmare. on a OHC engine you add 3 pulleys to your timing belt and a lot of cars also the add the 4th pulley of the water pump. OHV are just less complex and with a properly balanced motor their redline can still be relatively high.
"even though z06 costs less, GM is still not selling as many" In 2006, 34,021 Corvettes were sold. 34,386 911's were sold world wide. 6,272 Z06s were sold. I tried very hard but could not find the number for 2006 911 Turbo but I would venture to say less than 6000 because 911 turbos seem to make a lower percentage of 911s than z06s to Corvettes. Porsche does make a higher profit on the 911 than GM does on the Corvette, but you are wrong to think they are selling more 911s than Corvettes.
How can a V8 only have one single overhead camshaft in the entire engine? This video is on a v-block engine, not an inline. For a SOHC then it's one camshaft per cylinder bank, but there's 2 cylinder banks so it will have 2. Therefore if it was a DOHC, it would have 2 each bank hence the 4 total camshafts.
At 49-50 seconds the video shows a huge harmonic blancer/pulley crankshaft bolt being used for the timing gear on the camshaft. UPPS! Given it's such a detailed video, that had to be an intentional feature just to see if anyone would notice it...
well i remember hearing something about 16 valve compared to 32 (generally considered higher performance) having lower surface area in the valves and actually may of been a source of added performance. if you think about it having more ports may not be better than one single port, as its all going to the same place.
@DanM012324 It makes more sense to have 2 larger valves than 4 small ones, less things to go wrong. Why is it that American engineers tend to hate simplicity with a vengeance? All alloy was a good move, as was proper individual coil packs. They managed to keep that simple.
@IBM2217 Pushrods are found more on torque wise engine and don't rev up as much and aren't as efficient as makin power as a sohc or dohc. A 6 liter pushrod v8like this one makes like 400hp. A sohc could make like 475hp of so but at higher revs and it would loose torque but will rev higher. A doch with 6 liter pushrod v8 bould make 525+ hp it again would loose torque and could rev higher. But it always depends how they are tuned. More valves = higher revs n better vaccum
Right. That's why the LS7 weighs 250 kilos, or about the same as a the V10 in an M5. And also why the M5's V10 mocks the LS7 valve-train efficiency. Plain and simple, OHV cheap+simple, OHC better at everything else. No engineer would tell you otherwise.
@died4hislove I already told you why that design wont work. and conventional engines are inefficient because of primitive valve timing, friction and spring returned valves and that the piston ribs against the cylinder wall all the time. actuated rolling cylinder valve can fix the valve issue, a rocker piston on pivot off to the side in a curved cylinder can solve the wall friction issue and run without lubrication
lol we (me and my teammates at school) couldn't even make a proper animated explode view of a carburettor. well, it was as it was supposed to be, but some parts had a bad timing and position
fuel economy high? you can argue that in comparison with other v8s of similar size yeah its somewhat fuel efficient but come on! The 1UZFE is a MUCH more advanced, efficient and MUCH more reliable engine than the LS and it's an import I think GM stuck with the push rod design because it would cost far too much to re-tool the production line. I think GM caught on to antiquity of the pushrod when they developed the northstar. I think they keep the push-rod in the vette as vintage and/or tradition.
What laying off workers has nothing to do with how good the engines GM makes are it has to do with the fact that gm has too many employees doing jobs that foreign manufactures have machines do. Its isn't the industrial revolution you don't need an assembly line full of people to produce a car anymore. GM small blocks have never had any major problems .
OHV engines are much more simple than DOHC or even SOHC. so i would expect this engine to be able to go all out longer and more reliably. and the new Eaton S/C on the LS9 is so close to turbo efficiency its ridiculous. and there is no lag.
whatever you can't argue with people that think corvette is better than the greatest car ever, even harley-davidson goes to Porsche to get engineering tips, and theyre like the most "hardcore" american company that i know of.
it's not that we don't know, it's just we hate the engine, it's not a technical marvel. the bmw can get an acceptable fuel economy while being @ traffic jams in the morning. because it has variable adjusting cams. the pushrod engine wil reach the end of production in les than 5 years or close to it. heck, it doesn't even have automatic valve adjuster, meaning you need to see a docter every 20.000 m or so. while the bmw never needs to be check at it's valves, so who is better?

2005-2007 LS2
2008+ LS3
@milkman383 good call. The square intake runners are a good indication that those are LS3 heads. However the LS7 heads were had a casting like that. At the end the valve covers look like they say LS7 but that is not the correct oil pan. The LS7 has a dry sump

Cool video but this is an LS3. LS2 heads are "Cathedral" port heads. Still a nice animation!

WHAT? Are you trying to say that the cam is in/on the head in this engine?
The LS9, LS7 and manual Grand Sport LS3s are all dry sump.
Okay, not to sound stupid, but where can I watch like an instructional video that tells me the parts of the engine, what they do, etc?
Do all pushrod engines have only 2 valves per cylinder?
The DOHC ones seem to be more effective but theyre all 4 cyl...
@IBM2217
Pushrods are found more on torque wise engine and don't rev up as much and aren't as efficient as makin power as a sohc or dohc. A 6 liter pushrod v8like this one makes like 400hp.

is there a small plug in the rear oil gallery like my LS1....?
or is that just holden models (australia)
Great video! Was that designed on Solidworks?
Did you do all of the work in Solidworks?, then animate it through e-Drawings? Let me know, I am very interested. Thanks
what do you mean by offered in 05? Corvettes dont use carburetors for centuries lol.
Horsepower TV (or the other one) did a build-off between two teams... took about 1/2 an hour!^)
badass, which solid modeling software is this? Solidworks? or Catia?
@kcole939 this isa corvett engine,not camaro.
Neat animation.
About time the pushrod engine was converted to an OHC, though.
Wow 2 valves per cylinder! Very hight tech.
dude there is no carburators for like 2 and half centuries ago in the 70's and its an Ls2 motor the 400 hp motor that comes out 05 C6 and higher.
some people ask why i like chevy.. if this doesnt show how easy the chevy small block is than i dont know can help them see the light
i have this as my screen saver, but a vortec is animated first, then the ls2
anyone know where to find the Chevy R07 race engine screensaver, it's not on the Gm racing website anymore
While other people have dohcs chevy continues to outdo them with a single cam and push rods. Much easier to rebuild too
Really amazing! Is it possible to download this video?
Right. That's why the LS7 weighs 250 kilos, or about the same as a the V10 in an M5. And also why the M5's V10 mocks the LS7 valve-train efficiency. Plain and simple, OHV cheap+simple, OHC better at everything else. No engineer would tell you otherwise.
i wish they did this for every engine
@died4hislove I already told you why that design wont work. and conventional engines are inefficient because of primitive valve timing, friction and spring returned valves and that the piston ribs against the cylinder wall all the time.
actuated rolling cylinder valve can fix the valve issue, a rocker piston on pivot off to the side in a curved cylinder can solve the wall friction issue and run without lubrication
WHAT!? the car is a push rod????? its not even a SOHC it's a OHV.
.... i guess you cant argue with the end result.
its the best engine in America.
Super late to the party, is this availible for download still. I've clicked on the website and it doesn't seem to be active anymore :/
what software did you use for that and is it possible to build any engine(I4,I6;v6;8,v8 turbo, supercharged?
This engineer deserves the money hes making from GM
nice video. pls can i download this to my phone? hw can I get a video dat will be mentioning the names of the part.
where they are the rings pistons??????
From cars, to boats, to boat anchors, nothing lasts if you have fun, but SBC lasts the longest.
Those are L92/L76 heads....
lol we (me and my teammates at school) couldn't even make a proper animated explode view of a carburettor.
well, it was as it was supposed to be, but some parts had a bad timing and position
fuel economy high? you can argue that in comparison with other v8s of similar size yeah its somewhat fuel efficient but come on! The 1UZFE is a MUCH more advanced, efficient and MUCH more reliable engine than the LS and it's an import I think GM stuck with the push rod design because it would cost far too much to re-tool the production line. I think GM caught on to antiquity of the pushrod when they developed the northstar. I think they keep the push-rod in the vette as vintage and/or tradition.
we have an 07 Audi S4 and 05 Cadillac CTS, CTS is ok, just really cheap materials, the s4, is a 4 door car so it cant be comapred to the z06
@lobzdik 400 hp and almost 30 mpg...show me the better half thats as reliable, great horsepower, and amazing gas mileage out of a similar 6.0 V8 N/A
What laying off workers has nothing to do with how good the engines GM makes are it has to do with the fact that gm has too many employees doing jobs that foreign manufactures have machines do.

@MrTfournier I'm guessing he works for GM

it's not that we don't know, it's just we hate the engine, it's not a technical marvel.
the bmw can get an acceptable fuel economy while being @ traffic jams in the morning.
because it has variable adjusting cams.
the pushrod engine wil reach the end of production in les than 5 years or close to it.
heck, it doesn't even have automatic valve adjuster, meaning you need to see a docter every 20.000 m or so.
while the bmw never needs to be check at it's valves, so who is better?
tHAT WAS OUT COLD MAKES IT LOOK SO EASY
Very nice, God Bless American manufacturing!
you forgot some sealer on the sump gasket, oh wait gm never used it either :/
Those are LS3 cylinder heads...
