In 1676 Sir Isaac Newton wrote this in one of his letters „If I have seen further it is by standing on the shoulders of giants“. If there was ever an engine that this quote applied to, it's got to be the LS engine. Because the GM LS is the direct descendant and the modernized and improved version of one of the most Iconic engine designs ever made the Small block Chevrolet engine. The timeless original small block design was on the market for almost half a century and during that time it managed to set itself apart by being a class leader in many aspects. But by the 90s the small block Chevy finally started to show it's age. It was time for a successor. So GM introduced the Generation II of small block engines, but unfortunately without much success. The Generation II was largely based on the original small block, and just like the small block it started to struggle with the strict emissions, mpg and weight regulations of the 90s. So by the mid 90s GM decided that it was time for a clean sheet design. A brand new V8 engine. But the generation III and IV of the GM small block could have turned out very differently, because in the 90s everyone was talking about DOCH, V6 that, inline 4 this and even within GM there was this feeling present that the pushrod is a dinosaur with no future. But GM wasn't quite ready to give up their push-rod so to decide the future of the engine GM carried out some blind testing using their own executives which ended with the conclusion that the entire GM leadership preferred the pushrod engine. After driving two otherwise identical C4 corvettes, one with a pushrod LT4 and the other with the Lotus designed DOCH LT5 engine the management decided that the pushrod was staying.
But the other important thing done by GM after the blind testing is that they appointed the right person for the job. They didn't import engineers, but relied on one of their own veterans, Ed Koerner. A veteran of engine design but also a true car enthusiast, a drag racer and record holder himself. If you want an engine that will be loved by petrolheads, you better get a petrol-head to design it.
The GM LS engine premiered in the form of the LS1 engine in 1997 in the engine bay of the C5 Corvette. It made impact right after it's launch and won Ward's engine of the year award in the same year. In the following years the LS family would spawn several truck engines such as the LM, LR, LY, LQ, some of which make great starting points for projects. The generation IV of the small block started in 2005 with the LS2 and improved many aspects of the engine including the intake and exhaust and brought new technologies such as displacement on demand and variable valve timing. 2006 brought the Z06 C6 corvette and the 7 liter behemoth LS7 engine, which was soon up followed up by the LS3, perhaps the most popular LS swap engine. After this the horsepower monsters, the supercharged LS9 and LSA powered the Cadillac CTS-V, the ZL1 Camaro and the ZR1 Corvette and came as the final hurrah of the LS which would finally end it's production in 2017. Something that was heralded already in 2014 by the C7 corvette and it's LT1 engine.
When it comes to the specs all LS engines have 90 degrees opposed cylinder banks and a deep skirted Y shaped engine block which is a massive improvement in strength over the original small block chevy block design. The deep skirted block also enabled engineers to design 6 bolt cross bolted main bearings caps. The block also accommodates some very long held bolts for minimized bore distortion. All LS engines have forged powdered metal connecting rods with fracture split caps. An exception to this are the LS7 and LS9 engines which feature some very fancy titanium connecting rods. The heads feature hydraulic valve lifters and some very nice lifter guides that make it possible to swap cams on the LS engine without removing the heads.
When it comes to tuning, the LS engine family is a true champion because it has a lot of things going for it, it's readily available, reliable and has an amazing aftermarket. The block is strong and can take a lot of boost. If you want massive power the only thing your really have to get rid of are the stock cast pistons and powdered metal rods, after which the LS engine can take you to the stratosphere. The stock crankshaft, even though it's cast nodular iron, is very strong and can take 1000 hp like a champ. When it comes to the camshafts, many stock LS camshafts are pretty well suited for boost, except when aiming for obscene power. NA tuning the LS on the other hand starts with cams, intake and exhaust and some remaps.

Thank you so much 👶 Guys
When you said that overhead cams were better, I almost switched channels, as I have a Ford Econoline with a 351W, four-speed mt, & 9-inch wt posi.
This is similar to how you can build a Chevy wt a small block.
Why would I want or need to worry about timing belts that can break without warning ???
Sure if I wanted a high rpm engine, but that is a totally different design, like my Audi 4000 Q five cylender, which can spin all day ar 4000 rpm....
??,show its age.??.it was a chunk from the get go.like flogging a dead horse for 70 yrs..
ford only have 2 bolt patterns,from 1950,ish,big block,small block,&,ive never,,taken heads off to change a cam..
Bro you've gotta do the m156 next
I know some guys out there reliably making 700hp at the crank who have spent $2500 all in. Everyone should let that sink in. My own dad put a supercharger on the 5.3L in his truck about 15 years ago and ran it for 220000k with lots of towing before selling a healthy engine to the next owner. They're selling for 200 bucks at every junkyard in North America. There's no other engine that is even close to being as great of a platform for the backyard builder, and that is a fact.
My son-in-law has a camaro with a twin turbo set up with larger injectors and a few non so called internal changes and he has ran at the lapeer dragway in the mid 9 seconds. only minimal internal engine part change lifters and injectors.
200 HUNDRED BUCKS?
hold my bath boat...
Let me in, LET ME IIIIIIIIIIIINNNNNNN
700hp, but what's the top speed, and can the car turn a sharp corner? I'm old enough now that I don't care if the engine is a big dumb V8 or a small screamy turbo 4, but going fast in a straight line is still boring and always will be. Real roads have curves, and dragstrips need to start eating cheeseburgers until they grow some curves.
@@deusexaethera do you care about air conditioning and red-light to red-light drivability? 700hp is always fun. More so when you're not in a heat wave with no ac or trying to get over the cam lope or under the torque curve in a parking lot. I'm sure you know how building a car goes, you make it fast then deal with the repercussions. Make it stop better, turn better, all that jazz. I doubt dude's dad is diving through the canyons in his turbo hauler truck. Short answer is well, duh, yeah, it'll turn if you want it to. Different animal than slapping a turbo on a work truck. You must be one of those scca miata guys. I say you ls it.
@@deusexaethera Ok, but there's lots of builds where adding an LS improves handling (and braking). For example, if you pull a nineties Jaguar v12 out for an LS you have a lower, (200 lbs) lighter, shallower engine ... and also more power. Every dynamic condition in the car is improved. So rather than something that harms dynamic performance this brilliant little mill can easily be used to improve it. So basically, it's already on the dodgeball team.
"The only thing it can't do is, Fit the LS in a Civc.

I want to know are there any V8 push rods with 32 valve
Valentin Uiliqnow pushrod engines rarely have more than 2v per cylinder, unless you find a V16 good luck finding a 32v pushrod
@@valentinuiliqnow6198 other than prototypes, no. There were rumors of the blackwing engine going to be 32 valves and dual cams, one cam working exhaust the other for intake valves, and that it was going into the new c8. Fast forward to today, blackwing has not yet made it into the new corvette and blackwing turned out to be a dohc engine that went into Cadillac XTS. There is another engine in the works but signs point to it being a blackwing variant.
I mean the LS4 (I think) was a 5.7 designed for FWD cars, it may fit in the civic chassis with some mods

You know GM did a great job, when you have 5.7L that have the same fuel economy as 3.6L v6 or 2L inline 4 turbo that are produced 20years later.
HOLY SHIT ITS THAT GOOD?
@@Ivannbeats Only when it comes in stock GM cars which have cylinder deactivation
@@mayuravirus6134 then its not that good
@@mayuravirus6134 I have a 6 litre L77 engine in a Holden Commodore SS, it's regularly getting 9.4 litres per 100km, with no cylinder deactivation, and running on 95 premium, that's around 25 mpg in US terms, 30 mpg in UK terms. Not bad for a 360 hp engine!
@@timjohnun4297 my 08 rrs can get 30mpg if you use the auto like a manual. And it's a S/C 4.2. GM did nothing but take a pushrod engine that Ford placed on the back burner. The engine architecture was taken from the F.E V8. Or if you want to be petty, GM switched up AFTER their engineers went on to insult the Triton OHC aluminum block Ford engines, calling the junk and stating they'd never last. Funny part is the OHC Fords were on Ward's 10 best engines list and proven to be more reliable than the LS platforms. That's why most municipalities used ohc vehicles.
I rather like that GM stayed with pushrods, Dodge kept the Hemi, and Ford went with DOHC. Gives us all a nice variety to choose from.
Exactly, variety is the spice of life!

Love my junkyard ls1 in my 68 firebird. Running high 12’s and going 330 miles on 16 gallons of gas! No leaks or break downs in 7 years.
I was going to argue 7 years no break downs that you probably have a small block chevy under the hood .but after i figured your fuel mileage that is 20.625 miles per gallon ...are you still tunning a pontiac V8 made back in the 1968 to 1978 ??? Its pretty hard to squeeze 18 to 20 mpg out of a pumped up SBC ..so you would think you would need an 18 wheeler fuel tanker truck to follow you around if you had a cammed up 1971 455 s.d. Grand Pix With a Crane Fireball 500 cam . A friend borrowed my van and stalled it on the Santa Fe mainline and an Amtrak passenger train engine hit my van at around 130 miles per hour ..so my friend in remorse and all no money said here take the keys to my " lead sled " a 455 super duty 1971 G.P. with a Crane Fireball 500 camshaft and she goes ratta ta tat ratta ta tat vahaVarooom ba ..gee thanks i said ..this was 1977 and gas had already jumped from 50 cents to a buck .30 and im used to my 1964 ford econoline cab over no window 90hp three on the tree with a falcon inline 6 that got bout 18 to 20 mpg .i was living in williams arizona at this time and wondering if i can pump enough push juice in this demo derby car to be able to make it to flag staff to get more to make it back home. The whole left side of this lead brick was completely totaled out from the dog house to the left rear quarter looking like it had won the last demo derby ..but the fender wells were still intact clearing the 70 series goodyear wide ovals with plenty of room ..later my same friend want me to drive to denver to visit his mom and dad and says he will pay for all the gas ..anyway to my point finally . So its interstate all the way at Elevations of a mile high and more cruising kicked back with left handed cigarettes with the speedo bouncing on 80 ...and believe it or not as i figured and refigured the gas mileage from williams to gallup to santa fe to denver and back home we got 20 plus miles per gallon somwtimes 21 but never 22 ..but not bad at all for a big lead box doing 80 most of the way stoned in luxury ..hey did you know a pumped 455 super duty grand pix will top out up a 20% grade from as round 5000 ft elevation to 9,259 feet @ over 140 miles per hour ..i didnt either till one day after work from Seligman to williams i up and stomped her to the floor and left her there for about 10 miles right up the west side of bill williams mountain on I-40 ..must be why P.O.N.T.I.A.C. stands for *poor old nigger thinks its a Cadillac"

I thought I was a clever engineer, and understood how engines work. Then I started watching this series. It quickly became apparent I didn't know much. Thanks so much for helping me advance my understandind of the ice!
Dittoo !!
This engine is so well engineered that nothing afterwards (other then LS variants like the 4.3L and the new LT engine series) have come close to it's engineering & reliability on that front from the GM camp. Any newer 4 cylinder or V6 group IE: 1.4L/2.4L/3.5L/3.6L are horrible and are engineering nightmares. Having to replace anything on them are more then difficult to do unless you do them on a regular basis and have the required tools to do them fairly quickly. Without the dual camshafts, turbos, etc. these are weak by standard design and i've seen more blown turbos then I can count. I am ever so greatful to the normally aspirated ICE LS engines, a simple design yet customizable to our heart's content.
Say it Louder, at work.

When the LS6 engine came out (in C5 Corvette Z06), the 243 heads (that’s the casting number) out-flowed the best aftermarket LS heads you could buy at that time. Pretty amazing.
Please
I want to know are there any V8 push rods with 32 valve
There have been factory development projects. Ford had a 4 valve head for the Windsor. Oldsmobile had 4 valve heads under development for their big block
www.streetmusclemag.com/news/the-w43-oldsmobiles-dohc-455-v8-that-never-was/
The DOHC was a development of the 4 valve pushrod head.
There have been aftermarket multi valve pushrod heads. Three and four valve. Perhaps the most well known is the Gurney Westlake three valve heads. Unfortunately bling won't find an image. The one below is for a Corvette motor
www.corvetteactioncenter.com/specs/c6/corvette-ls7-engine/ls7-engine10.html
One problem with 4 valve heads on a pushrod engine is pushrod clearance issues. Plus one pushrod opens two valves. Additionally the exhaust valves usually need a secondary pushrod between the idle rocker arm and the one that opens the valves.
The Z06 was amazing light with an aluminium hydroformed chassis using a lot of space but extreemely rigid and with plenty of light titanium parts in the LS3 engine: the best affordable supercar at the time: light and reliable, just the opposite of the heavy GT-R trouble. Too bad the Vette only dealer network wasn't more developped and dynamic in Europe and direct import a homologation and operational nightmare. With similar good support and guarantees, it could have matched 911 volumes and resale value here...
@@valentinuiliqnow6198
Some V8 desiels are 32 valve pushrod engines.
Very true brother
This channel is super underrated!!!
It is extraordinary. If you do a little homework as you watch, this is a university, upper division level class in engine design.
As a proud LS2 owner, this video is an educational example of why this iconic engine is such an “in your face” powerhouse compared to other manufacturers. Screw DOHC engines with their complexity. I like my compact, big displacement V8 that can make tons of power with simple mods. Oh and it still gets 30 MPG on the freeway. Well done, GM. Truly are legends.
Love this comment. Pushrod V-8s are my jam as well. Such beauty in the simplicity and capability
wait ur serious 30 MPG WHAT
@@goshbaby8531 yup. Dead serious
Agree with you. I am blown away how good the performance of this engine family is.
My buddies have gone to exotic DOHC engines. They um... dislike their maintenance bills.
Keeping their bell housing bolt pattern is one of the things I loved about Chevy growing up in the late ‘60s, early ‘70s. I took my 250 inline 6 out of my Nova and put in a 283 V-8 and didn’t have to change anything other than exhaust and motor mounts. Ford and Chrysler used to change bell housing bolt patterns with every engine family, for no apparent reason, which made trips for parts to the salvage yard very frustrating. I put a starter in a friend’s ‘69 Ford LTD 390 and they had THREE DIFFERENT STARTERS for that year. With my inline 6 to V-8 Nova swap I used the SAME STARTER and radiator. This made working on Chevys far less irritating and I found that I cussed Chevy engineers much less than when I worked on friends’ Fords and Mopars.
Yep
SAME! Took an intact 235 bottom end, plopped 292 truck heads on it, and nova 250 intake and exhaust from a buncha parts cars and made a runner.
Exactly! The ability to mix and match fairly easily was awesome
@@darrellhay Love Fords, but that parts interchangability is one of the things that makes Chevys so loved.
From Russia with love!
As an enthusiast I will always praise the LS small block. As a side note I am glad you stated this engine family isn't called "LS" from GM. I didn't know that until recently.
I am blown away every time I drive my LS powered car. It is amazing and the engine never feels like it's running out of steam for the streets. Of course that's were these engines do their best.
Great engine, they live as a swap in many other car brands. They are cheap to buy and repair and there's a lot of aftermarket. They are small and lightweight for its displacement, power and torque and its stock fuel economy in lightweight applications is really good. Oh, I forgot it, GM transmissions help a lot too.

Excellent video. You have covered pretty much every aspect of LS engines.
Amazed every time I visit this channel, much love from Germany!!!! ❤
About a year ago I bought my fathers car off of him, I bought tons of equipment and a really good LS from Texas Speed. This past fathers day I gave it back to him and said I was done with it saying it was a piece of crap now. A very good Holly system was on there and it looked stock as hell with all original dials working.
He suspected that I did something to it. He took it out for a ride. The hidden camera got his reaction and I couldn't stop laughing for a while. I made sure that all luxuries would work as in A/C and I improved the sound system with a bit of a simplistic radio system because he's a bit of an older guy. The power remains 1K HP and a good amount of torque. I used a blower instead of a turbo as the heat from a turbo is hard to manage.
When he came back I could tell he was choked up and not wanting to cry in front of me but I asked, "How was the ride? Seems like there there may be repairs we'll have to do."
Then he hugged me and silently wept as he wanted a fast car of his own.
Interesting story about blind testing of engines. When I was in Germany working for DaimlerChrysler, MB engineers were asking for money to develop a V12, but executives wouldn't have it. So the engineers transplanted a BMW V12 in an S class, disabled the hood release, and let executives drive it. They all loved it compared to the 5 liter V8. When the engineers opened the hood, they got the money to develop the V12.
A perfect example of how the World would be a better place if run by Engineers instead of Accountants.... $$$$$$$$$$£££££€€€
GM also installed a BMW V12 in a Shivrolet Caprice in the early 80's.
A BMW v12 is far better than an LS. Imagine if they heard of V12's in the US.
Thank you for video. From Russia with love)
Hey, that's my car at 22:06 ! I'm obviously a big LS fan, the physical size and weight were huge considerations when swapping out the straight 6 in the Triumph. I also have a 4.8 single turbo LS in a 1950 Chevy PU, that engine is pretty stock, has over 200k miles on it and runs perfectly. I'm really enjoying the channel and am having a blast going back through your catalog. Thanks for making great content and keeping me entertained!
What a great channel, informing, interesting and so well put together, the narrator has a great speaking voice. I love stumbling on great channels!
The big "DUH" with the trans bolt pattern is not for entheusiests, but rather they didn't design new transmissions to go with the new engine. They had to mate these to existing transmissions which just happen to have the same bolt pattern throughout time....unless GM goes away from a rear drive V8 it's unlikely that any future rwd V8 engine will obsolete that bolt pattern for that same reason.
There's a couple reasons for the lifter pockets, one of which inadvertently supports the enthusiast market. GM dealerships service vehicles. Lifters and cams are serviceable parts. The less $/time spent on servicing the vehicle the lower the cost, which means the higher the residual values of the vehicle which in turn means they can charge a higher initial value.
This amazing video really changed my view of the LS for the better, thanks for the enlightement🙏🙏🙏
The rap at the end was hella badass tho lol and I ain't even from 'Merica.

Great Vid as always. In D4A we Trust!!!!
It's crazy to hear about these places (Milford) and the GM Tech Center (Warren) on the Internet and having passed both multiple times already this week. lol
Push rod engines may be prehistoric but they work well enough Ford's new 7.3 gas will be a pushrod engine.
The LS is an example of ends over means. It's more important WHAT the engine does, than HOW it does it.
Yes, but what the pushrod engine does is burn more fuel for a given power output, increase reciprocating mass, and increase emissions. Having worked for one of the big 3 during this time, the problem with all of these executives is that they are too provincial; Detroit streets are 90 degree turns separated by 1/2 mile straights where 0-60 is the only performance criteria these executives care about (American cars can barely stop or take corners), and they have no idea of what makes a good car. Which is why they need import tariffs against the Japanese and Europeans. And why Chrysler went bankrupt three times and is now a subsidiary of Fiat Peugeot.
@@hunterjohnson7393 such an odd statement. You know most American cars today don't weigh 7,000 lb like they did in the seventies right. There are plenty of American cars with significant track times including many with records right now all over the world.

@@ashes2ashes863 I’m wondering what 70s cars you are talking about that weighs even close to 7000 lbs. Even full size cars seldom weighed over 4500 and my’71 Nova was under 3200 lbs. Midsized cars were between 3500-3900 lbs. Today you’d be hard pressed to find anything midsize or bigger that is less than 4200 lbs. and many are over 5000. Electronic everything and safety equipment (multiple airbags), computers and sensors, sound deadening, etc., etc. The older cars may seem heavier but most of that was less power, fewer transmission gears and most cars didn’t handle for crap. Funny how 50 years of technology can make a heavy pig make it feel like it’s driving on rails.

Funny thing is that pushrod engines were developed after dual cams
@@Mr_Roboto No, the first overhead valve engine used pushrods and was developed by David Dunbar Buick, the founder of Buick, which would become the beginning of General Motors. Dual camshafts were used on T-head (crossflow flathead) motors only, not on L-head (reverse-flow flathead), and T-heads use the two camshafts on opposite sides of the block to drive the exhaust and intake valves via a short pushrod. Learn your motor history.

Drove a C5 Corvette across the USA and was getting 25-28 mpg between 80-100 mph. I love the LS engine. I have driven an LS1 and an LS7 and both pull very hard from idle.
6 speed manual ??? Gearing
Yeah the MPG is great. I have an 04 GTO with long tube headers, exhaust and a tune with a 6 speed manual. It's easy to get 30 MPG at 80 MPH with the AC running.
That's the argument that I always make with these chumps I think you have to have four valves per cylinder for proper efficiency. Pushrod engines make more torque and when your idling across the United States at 65 mile an hour that's more important than horsepower. When you could tap the gas pedal everywhere you're going to get better gas mileage you regardless of what efficiency A 4 valve four-cylinder overhead cam engines going to run at.

Had a 75 Monte Carlo, 350, 2 bolt main, Quadrajet, Auto, 20 mpg hwy. Loved that car.
The stock Gen IV rods have been proven to able to hold a good amount of power. I had a LS3 at 700rwhp for a while.
LS is one of the smartest things GM ever did.
They just copied Ford designs
@@davidgraham7325cope
I remember at the time when they where designing the ports, that alot of racing head porters would get head samples to help develope the head ports and that's how they came up with the cathedral ports. A bunch of red necks with porting tools came up with that excellent port that started the LS legacy.
I recall seeing a TH-cam video a few years ago about a Mercedes-Benz factory worker hand building an AMG 6.2L V8. Everyone commenting was all "ga ga" about it. My response was: Let's see Benz do that on a budget of only 2x the cost of a good LS engine that make as much or more power and is likely more reliable.
Hello from Russia! My comrades want to give you a samovar filled with cranberry vodka!
Best video so far. Very good LS history and explanation. Well done!
Long live LS push rod. Real irony is a Slavic dude, who lives in Europe, talking about American push rod engine. LOL.
watched a few videos and subscribed I Love this guy!!!. Informative,entertaining, comedic and the visual presentations!! is all there man keep up the awesome content.
Love the in depth videos! Happy to have found the channel!
This platform has been used to create a twelve cylinder motor here in Australia which goes even further to proving what a great design the LS is 🇦🇺
How s that?
In the early 2000 gm was developing a V12 version to use in a high spec Cadillac and even put one in a Escalade. The program was eventually dropped....but I wouldn't be surprised if the plans for it got "escaped" because I've heard of a few V12s developed from the LS
I wish gm would do a brand new I 6 that would be awesome we need more in line 6s
The new standard Bronco and Bronco Warthog should have came with turbo inline 6's IMO.
4200 vortec?
No need to, Cummins has perfected the I6 engine.
They have a new small Duramax. 3.0L I6.
@@kevin9c1 Interesting, Isuzu historically makes some good inline Diesel engines.
Overhead camshaft motors have been trading extra complexity and engine height for higher RPM since 1913. Since pushrods can go up to 9,000 rpm now, (if you're very fussy about the valve springs), the need has diminished. (In a V-8, overhead cams make the motor wider.) "Simplicate and add lightness" has a lot going for it, so pushrods are going to be good as long as internal combustion survives.
DOHC multivalve is superior. More reliable, more efficient, more power. That is why they are used.
Excellent video. I knew a lot of this info but you gave me much, more and that is always appreciated!
Great video! I am old and have had many of the popular muscle car era engines (ford chevy and the hemi) but my FAVORITE all time v8 is the ls3 that is in my 2011 vette. LOVE LOVE LOVE that engine.
Interesting content my friend, love the history and knowledge
The single best thing that GM ever developed. Brilliant piece of engineering.
Bro, I give you much credit for laying down those rap bars! Also, you are very knowledgeable with the vehicles and engines. Thanks for the time and effort you put into these.
love this video never knew the history of this engine. i have a 2005 gmc sierra with the 5.3L love it
From Ukraine with love! 🤜🤛
Yet another outstanding and informational video from d4a. Love these videos. Can't wait to see the next video. Maybe h22?
Im so happy to stumble on this channel
I'd say the 6 bolt mains and the rectangle port heads it is reliable durable and with maintenance it will last a long time
From Ukraine with love!
Never thought I'd love so much, a Slavic guy explaining GM pushrod V8s as much as I do! You frickin rock brother!!
Love your content my friend. Just watched your LS, and the EJ20/25 videos. Just awesome. Super informative, entertaining, and a lovely sense of humour too. I really like how you give a lot of facts on the engines, and leave the tuning info to the end. I'm an engineer, and I have projects like re-engine for a forklift, or for a crane, or to build a co-generation platform. I don't actually have time to do these projects (!), a lot of them are in my head, but I'm always looking for engines for this or that. Sometimes I want super simple. Sometimes I want something else - like a very short engine or a very low engine, or a very fuel efficient engine, or a very quiet and smooth engine, or a CHEAP engine, or an engine that can be fixed in the jungle with no tools - like on a Sherp. To me, a lot of the tuning stuff that youtube is full of is just ridiculous ! My focus is to have equipment that does useful things, rather than cars that drive very fast. I wish to hell motorcycle engines didn't have their gearboxes cast together with the engine crankcase. We would have such a variety of engines in the smaller sizes to play with.
The Raps! hahhahha. Keep up the great raps.
Well done my man! As always, well done...and informative! Somehow I feel very patriotic now and feel the need...for speed! 🤣🤣
The LT -5 is my all-time favorite engine. It came in the late Gen-4 ZR-1's I believe...
I had a 1996 Z28 Camaro. (LT1 5.7L)
It had a mean growl.
It easily would spin wheels when I wanted to.
Great explanations on what the mills can do etc.
Many thanks
Lt5 was GENIUS. Made more POWER than anything else in US .
Good video. Keep up!
One small correction:
stock gen 3 rods/pistons can handle up to 750hp. Gen 4 rods/pistons can handle up to 1000hp.
It' s dyno proven many times.
Piston ring gap and dual valve springs, after market ecu and tune, 100 octane fuel or E85 and it s ready!
Doing it on the dyno, vs doing it in a car for thousands of miles are different stories.
@@leftyeh6495 yes but both stories end up with the same result. Ls can handle that power for many miles
OMG! This was totally awesome. I learned so much about the LS engine and pushrod versus overhead cams. And lots of other concepts. You put it all together so well, and it was so easy to follow. This is the best overview, history and explanation of the mighty LS.
Sooo, with titanium here and aluminum there and cast iron and steal everywhere else, I was wondering about titanium pushrods.
So I went down the rabbit hole and found out what a bad bad idea that is.
There might be a slight gain by titanium being light. But it would need a metal insert on each end because it's not tough enough. And it's also very springy. Very. The last thing you need for a push rod is a spring! That's mainly why they're not used.
Thank you for your hard, diligent efforts, once again.
Amazing video! Such great info
I'm building a new LS engine at the moment actually using the new dart pro iron block.
A 434 with a high end cathedral setup.
Block is rated to 2500-3000hp.
Better buy 2 Borg Warner S475 turbos
Goes up to 8.1 liters actually, vortec 8100 series, 496 CI of American freedom. I have a few and I love them for making power.
The 496 or 8.1 is not a LS. It's the 7th gen BBC. It was the last BBC made. Looks kinda like a LS but it is a BBC.
I also have an 8.1 in my 2001 GMC that I bought brand new and just can’t give it up. I’ve pulled 60’ tall trees out of the ground at idle with the brakes straining to hold it back.
Really enjoyed this, as a proud owner of one of these engines. Good job.
Great video! grew up during the intro time of LS Engines so obviously I fell in love with it. Haha
Now I want a LS engine for my Tacoma lol. Awesome Video. Thank you
LT1 did have 5 head bolts per cylinder though which is pretty nice.
Dude you have the greatest sense of humor!!!! I love these videos !!! And the rap was DOPE!!!!
I love the detail that he goes into with these engines.
From Russia with love.
As a Brit, I prefer Pushrod V8's for the sound, simplicity and instant power response. I also enjoy high revving i4's but I don't see them as " Progress " I see them as an option. I'd happily take up an old small block for a comfortable cruiser or work horse pick up truck over any of the newer engines as it's simple to work on and rugged.
5 out of 5 LS overview, thanks, exactly what I was looking for.
Thank you for solidifying my reasons for going LS on my 63 C10
Can’t wait for your EJ20/25 vid man✊🏽
Another fantastic video!
But don't forget the fuel economy for the power. Even without considering the power - LS swaps very often improve fuel economy!
Thank you so much sir!!! go figure youd give me this awesome vid over the other main stream guys I watch XD
Excellent breakdown and explanation!!!
Hello from Russia thanks for the permission to translate
Thanks for all the info!
love your enthusiasm!
!!!YEAAAA MURICA FINALY GOT IT'S CHANCE!!!!. Man I never thought these day would ever come the only bad thing was when the LS was replaced with the LT "says the guy with a 6th gen camaro". But the problem with these engine is there fuel management system or cylinder deactivation or how I call it Vtec gone wrong .... I know I know is not the same thing but they both target the same purpose, maybe you can give these topic a shot at some point in your channel at any time. Thanks for the Video keep up the amazing work. 👍👍
Very easy to remove those systems
@@LandonRoy-cv9rt Do not remove the VVT and the.AFM as they work well.Change the oil as per the owners manual and they will last as long as the well oiled engine.
I love these videos! A video on the coyote 5.0 would be sweet
Great informative video 👍🏻👍🏻👍🏻
