Everything about that checks out. V6 engines are also harder to balance, so they require a little more attention there from the manufacturer. People, particularly Americans, love v8 engines. It's a huge part of our culture to value them more highly than v6s.

Two things: Crank-driven oil pump, and Cross-bolted mains in a long block skirt. Those two things alone make the LS the strongest engine out there, and make it super-popular. Race engines use main girdle kits for the same reason - stiffening the block lower-end and increasing crankshaft support

[@lettheboywatch3100]

@itsabig yes SIR, though Chevy boys will die before they admit it, the LS is a stolen designs haha. From both Ford and Mopar, it's clear as day the mighty Cleveland had alot to do with the LS. Love it haha couldn't have said it better myself, Chevy has been stealing designs since forever.

[@albertgaspar627]

GM has a long history of a deep skirt Y block design, to add strength to its aluminum blocks. The Buick 215--which was sold to Rover--is an example. The V6 made from it, which became the Dauntless in Jeeps and the turbo version in the Grand National, also had the deep skirt even though it was cast iron. The deep skirt creates a larger volume in the crankcase, which also helps the piston speed--as it comes racing down to BDC, it isn't compressing the atmosphere inside the crankcase and causing resistance, since there's more room for that atmosphere than in a normal V8. I believe in America, Ford made the deep skirt popular with its 239-272-292-312 Y block engines that followed the flathead and were a bridge to the Windsor small blocks. As for the comments about the Cleveland...guess where the Cleveland got its canted valves from? GM exec Semon Bunkie Knudsen brought some engineers with him when he went to work at Ford...after the Chevy Big Block went to canted valves from the old W 409 design. But its also thought the 1st generation Chevy small block borrowed heavily from the 331 Cadillac that came before. The LS head design is suggested to copy the NASCAR Ford head design. www.stangnet.com/mustang-forums/threads/ls1-heads-on-a-ford.730454/ www.jalopyjournal.com/forum/threads/ls-engine-a-copy.458032/

I'm fortunate enough to own a LS7. It's a real gem of an engine. And now, GM dropped the price, at least here in the US, for a long block crate engine, from about $17,500 to about $10K-12K. Hot Rod magazine bought one for a project. Broke it in then did the same SAE ISO witness certification correction the engine was rated with. About 520-525 bhp and about 490 lb-ft torque. And it has a dry weight of only about 438 lbs. It's an amazing piece of power plant.

Fantastic video Scotty! The content development on this channel has been unbelievable, and I truly hope it continues. Thanks Scotty and Haltech.

[@2secondslater]

You will notice that the timing cover has no locating dowels to the block, on initial assembly, it is important to fit the timing cover with seal installed without tightening down the bolts completely, then fit the balancer, then complete tightening down the timing cover bolts, this ensures the timing cover is centred to the balance and minimises the chances of oil leaks.

[@geoffmooregm]

There are a few tools now that solidly locate the cover to the crank snout and allow you tighten the cover down and install the seal after. A similar operation must be done with the oil pump. You need to remove the cover on the pump, shim it between the rotor and case then tighten all the bolts and remove the shims.

[@albertgaspar627]

Here in America, its a different story. We can find a #10 block like your mate did, but its just as easy to find a "Vortec" block in a junkyard from the 1990's, the heads flow better, it already has a roller lifter camshaft (no need to worry about enough zinc in the oil to keep a flat tappet lifter from killing itself). Hot rod parts for the "1st gen" 350's are dirt cheap now, since everyone is going for the LS engines. I can slap together a 400bhp engine for less than $2,000 US. Our Dodge 360, on the other hand, has the lifter angle used back in the 1960's, which was borrowed from the Poly A blocks (which may be similar to what was available in Australia), which in turn came from the 1st generation of Hemi engines. In other words, its not a great angle for the pushrods. Finding hot rod parts for it, used, isn't as easy as the "Chev 350"--i can go to a "Tag sale" at someone's house, and find parts someone bought once to hot rod a Chevy 350. Its actually a euphamism for anything common, easily sourced, and chosen more often than not to do a job.

In one way, the LS is just like the old 350 small block. They both make decent (although not always earthshattering) power, they're both relatively reliable, they have a huge range of aftermarket parts and services, but mostly...packaging, packaging, packaging. They fit into just about anything. Not the most up to date design - but sometimes, old-school tech like cam-in-block and pushrods is good enough, while keeping external dimensions to a minimum.

[@obsidian....]

It's crazy how glad we are (well a lot of us at least) that GM didn't go the way of Ford and the rest by chasing the overhead cam (yeah they are doing it with Cadillac but that's about it). I know Hemi's are still pushrod but without the LS/LQ I don't know what everyone would be doing right now in the engine swap/aftermarket area. Like you said it's the packaging.

Improved 6 bolt, cross bolted mains combined with the BBC style valve layout meaning no exhaust valves right next to each other. Two of the weak spots you run into making big power with boost on a factory SBC are the saddles/block itself which usually self destruct before reaching 1000hp and head gasket failures from the hot spotting between the center cylinders because of the eiieeiie valve layout. For people wanting to make big street power a ls with boost is the most economical choice. As well SBC always were the number one choice swap motor. Now there are literally millions of LS engines built and its been over 2 decades since the last Vortec style SBC was offered. So as far as availablity the LS wins there too. Then you look at size and it wins again compared to the huge ford mod motors and hefty hemi. And aftermarket swap support compared to the mod motor or the hemi is night and day. So just like the orginal SBC, cheap, available, lots of aftermarket support for the engine and swap.

Did a lifter in my vz ls1. Did have vcm cam all the good gear convertor 3.9s raced it regulary. stripped it wacked new ls7 lifters new cam oil pump timing gear etc. Still had hone marks in the bores and it had done 187k then. Made same amount of hp as it did with larger cam. Ls is king

Hey, lots of budding mechanics started with the lowliest of powerplants. Learn the fundamentals.

[@karljay7473]

A few key things: Alum block with 6 bolts per cap and a compact design. That gives a great foundation to build on. It would be interesting to compare things like weight, power, stroke, to things like SBF and modular engines.

How many times have you heard the term “LS-swap”? What makes GM's LS series so popular with drag racers, hot-rodders, drifters, modders and tuners alike? We dive deep to find out the reason why this particular engine is so many people's favourite. This is quite a long video so if you want to jump a particular section, we've included some shortcuts: Engine Overview: kzbin.info/www/bejne/rX69eGqke91gaK8 Tuning Options: kzbin.info/www/bejne/rX69eGqke91gaK8 Engine Teardown: kzbin.info/www/bejne/rX69eGqke91gaK8 --------------- What engine you'd like us to cover next?

It would have been cool for you to talk about the difference in uses between the LS and LQ. I only recently (within the last two years) found out that you didn't get LQ's in Australia. I know it's just iron vs Aluminum but...

[@randalllawkin]

Ka24de lol

[@daveverdonschot7956]

Soooo.... What actually is it that makes this engine good? The simplicity alone doesn't explain al of it... Nice to work on and sturdy design, but what is it that makes it perform? Is it an efficient burning engine that can operate safely with a high compression ratio or does the power just come from displacement? I wouldn't mind a bit more detail.

[@lachlantaylor9888]

[@doonhkahn]

Scotty, you totally skipped talking about the high flow port design, the large cam lobes, roller lifters and beehive valvesprings that combined allow for aggressive cam profiles and high rpm with good reliability. These things together with the strong bottom end and fairly simplistic design are what makes the LS platform such a good engine. Easy to make reliable power. That, and just like the old gen 1 and 2 small block, there are millions of them out there for the choosing.

[@kayhoww]

[@pauljs75]

Also one of the few things at GM where the accountants or recent engineering undergrads wanting to do a thesis project don't seem to be involved in the design. So it's proof that some things can be done right if not tampered with and kept simple. And because of the old school KISS aspect and reliability, sometimes it gets swapped into other cars from expensive brands to replace their over-engineered engines because the owners simply want to drive the car instead of having to pay for them again in parts and labor of an ongoing repair project.

[@flweeptwo]

A tip for anyone looking at a future swap, there are 2 generations of LS, not including cathedral/rectangle port, the gen 3 and gen 4. They're pretty compatible except for 1. The gen 3 has a 24 tooth crank reluctor while the gen 4 has a 58 tooth 2. The gen 4 have stronger rods 3. The knock sensors on a gen 4 are moved to the side of the block instead of the lifters valley Both are good choices tho

[@Vasquezz28]

Also the engine in the trailblazer SS is a gen 4 engine with a 24 tooth crank reluctor

[@KrikZ32]

Awesome video I'm about to pull down my series 1 ls1 with what I think to be a blown bottom end this video is a huge help.

[@thiosemicarbizidebenzoylal2921]

Its flow at low rpm. A engine is a air pump and LS engines are the best pumps out there. That's part of the reason for torque at low rpm.

[@loludied552]

I think the reason why the LS still uses pushrods is mostly to reduce manufacturing cost, instead of making it significantly smaller since a well designed DOHC that uses bucket shaped cam followers, and small sprockets when connecting the camshaft to the crank wouldn’t add much height to the engine as in no where near as much height or width compared to a typical small block V8 with DOHC A DOHC engine would be able to produce about 20% more power and possibly more torque down low if it uses variable valve lift. The downside of a DOHC is that it’s expensive to the point that it’s cheaper to make a larger pushrod engine that produces similar power output especially if a manufacturer is going to be producing tens of thousands of these engines per year.

You name any pushrod you like and I will counter with a smaller OHC engine that will blow it away in terms of power and torque per cubic centimetre of capacity and be better at fuel efficiency and emissions in the bargain. Pushrods are a dinosaur in today's technology!
