Watch the ‘ENGINEERED’ series from /DRIVE about the LS. Tom Nelson from Nelson Racing is an interesting guy to listen to. I think it’s two videos, if I remember correctly.
Its insane how much knowledge is in this guys head. He's not reading a script or cutting edits, hes just non stop delivering deep insight about engines
This guy really knows his stuff. He explains in detail in a way that’s easy to understand. I learned way more in this video than any other video/magazine/forum that I’ve ever watched/read. Props to this guy. Great video!
@denairxtx But my plans have changed. I am just planning on doing a full exhaust, a cam swap and when I have the big boi money, get an A&A supercharger.
I am sitting here watching this man explain this like an absolute God. Every piece or process is a work of art. He squeezes every last ounce of hp out. I would gladly work under him if the least I could have is his knowledge on this topic. I saved this to have a guideline to build my LS. Thank you.
I've watched at least a hundred 'Build videos, and this is by far the most articulate presentation of a 'Build that I've ever seen. I'm inclined to trust this guy on my upcoming LS NA project, and I appreciate that he uses so many premium parts and treatments combined with attention to detail. Often, I'll talk to a builder who will tell me, 'you don't need this, or you don't need that.' I'm judicious when subscribing to TH-cam channels, but I didn't have any reservations after watching this.
There is need, and there is want. Some things are not needed but wanted. If it is just for daily driver, most of the stuff isn't needed, there are good midgrade parts that are fine for that. But if you can afford the better stuff, then there isn't anything wrong with some piece of mind. I will be trying to purchase the johnson lifters and stuff, i may be inclined to pass on the CP pistons and get the same forged alloy from summit or something as I still want some high performance parts for when people in dodge chargers that thyinnk they have the fastest cars in the world just because they have lloud exhaust are not able to beat me in a race. i will floor ir once in a while, ecpecially on the NJ turnpike. And when someone is trying to show off their speed i want to be able to blow them off the road.
I've been watching LS videos for like a year now and this man out here bringing up stuff I've never ever heard of, "surge calculations" "valvespring heat" ect. He's probably forgotten more about engines than your average gearhead will ever know.
Donnow if you’re smiling because you love what you’re doing so much, or because of the great dude you are… best explanation of relatively complicated technical stuff. I can hear you explaining about cucumbers and not get bored… many thumbs up.
I just was given my mothers WS6 for Christmas. I drift and this gave me alot of things to consider. Im looking for a street/drift set-up and this is perfect. Here i was thinking i was gonna have to think about a blower. Thanks for saving me that nightmare 😅
This man is one of the most knowledgeable automotive geniuses of our time. He is under appreciated and I wish I could have the opportunity to stand at his side while he builds masterpieces. He is intelligent and still humble, something not common in today’s world. Maybe some day I could meet him and work with him.
Those LS engines are very impressive. I thought my LS3 was a hoss until my buddy built an ls7 how it made 623 wtq and 586 whp and it is close to stock they are impressive. I had to spend a lot of money to get that out of a small block Chevy.
I am going into high performance engine machining for college this fall of 2020 and this video has taught me so much that it is insane and I'm only half way through it! I am definitely revisiting this video later on down the road. I plan on building a N/A built 5.3 or 6.2 depending on what I can afford for my final project and this has brought to light a lot of things that I have never even thought of, things like all the different coatings to reduce friction. Or the AFR heads that flow and force the air/fuel mix toward the plug for a better burn. I probably would have never known about the longer rods with stroker builds. Crazy what I have learned so far.
Similar build to the LS3 I built for my Trailblazer SS. A 4.065" bore 4" stroke with stage 2.5 WCCH LS3 heads, 240/250 .623 .617 114 cam, 11.8 CR on 93 octane, stock Escalade L92 intake and stock throttle body. The intake and throttle body is what was hurting me the most but all aftermarket intakes sacrificed too much mid range for top end power. Best option was to port the stock manifold but I didn't. I'm building a LQ9 for my Yukon now and have some CNC 243 heads, a TBSS intake and 90mm TB I'm going to actually have ported before I put it on and a BTR cam most likely the Truck Norris because it's a 212/22x with .560 lift so not really crazy duration and lift so it should really work well. Awesome video excellent information.
You can totally hear how smooth she sounds with the longer C/R stroke, right around 3.5K these heads are just flowing like crazy. Makes my 799 look like a kid hahahaha Great technical explanations, much appreciated.
Excellent build just like I used to build them head work and all 350 4 bolt main isn't 600 roller cam needle roller rockers 13.5:1 JE forge true fire slot pistons M/T aluminum rods heads be me looked just like your heads when done all ports gaskets matched to tunnel ram intake and hooked headers 2 holley 750 double pumper dual squirter vertex mag but in late 60's early 70's im 72 and was always a little bit head of my time. Great build you are a true artist !!!
Good one Mike. The details on the 6 bolt mains and the stroke limit recommendations @ at 4inches, probably helped out a lot of people. I had similar questions back in the day before I started hunting for sweet spots on the LS side. Curious if you guys will do a video on the 4.6 2 valve blocks. Sold my ls6 vette and starting to dig deeper into my 01 Procharged Bullitt but the 4.6 guys rarely share details on the square bore/stroke specs openly as you do. Andrew Lavender (on TH-cam) does a great job detailing this like you do, and your attention to detail as a Motörhead is what keeps me coming back here.
I like this guy I get really sleepy with most people trying to explain it but the smiling LS Guru really keeps my on my toes learning a lot thank you 🙏🏽
He’s a great teacher with an insane amount of knowledge. Doesn’t say too much, and calm. Unfortunately I’m not ready for this course lol where’s the 101 class?
Hey mike! Always smiling and passing on the knowledge. It’s Great to see ya putting videos on the tube. We gotta get more kids into this stuff instead of being scared of it.
I used to get annoyed when I would hear someone say you should avoid 4.0" or more than 4.0" of stroke on an LS, and how the pistons fall too far out of the bore at BDC. I used to try to correct those people, and show them that you can run 4.100" or even 4.250" stroke with stock sleeves, but it does no good. Now I just sit back and enjoy the feeling of superiority and knowing my big brain has learned something a lot of respected engine builder still haven't figured out yet. Seriously though, nice video. Way better than the one where Hoonigan attempts to build a 700hp LS stroker....
@@motoiq I edited my comment to be a little more clear, but I am making fun of professional engine builders that say that 4.00" of stroke is the limit on a stock sleeve LS. I think it's because a lot of people don't thoroughly understand how a piston works, or just have bad information from their piston sales rep. Whatever the case, the fact of the matter is that you can run more than 4.00" without tearing up the skirts. There are 4.100" and 4.250' stroke LS engines with stock sleeves and the piston rock at BDC is the same as a 4.00" stroke combo. I'm pretty sure they all use Wiseco pistons too...
I remember this dude from the Sport Compact Car Dave Coleman days doing the Lord's work with a 300ZX. I moved to Japan and just got completely worn out on JDM cars (not that cool when they're everywhere) and got into domestic U.S. stuff...and BOOM here he is.
I have a 8 bar LSX with 5.3 and 6.0 parts in my 2005 yukon XL. Making about 400 flywheel hp with stock intake and 6.0 injectors. Really great motor. (I went with the factory exhaust manifolds and deleted my cats, kept the muffler and 3" piping)
One thing he doesn't mention is GM actually lengthened the cylinder bore on the LS7 to limit how much the skirt of the piston actually left the bore to stop the piston rocking and wearing out the bore it self. Regardless of what you throw in it. This eventually causes pre mature wear. Stick to the stock stroke or get an LS7 or LSX block etc etc.
Add .25" stroke as GM did on newer 6.7 motors available in trucks. Nice torque, & no skirt problems. But ... In my opinion, from decades of hilevel experience, BE WISE on who machines your block and matches parts to same!!!! Nobody talks about this. If machinist isn't TOP NOTCH GUY, then your parts are going to be destroyed, and you will be wondering WHY.!!!! In summary: a few thousandths of an inch are CRITICAL. !!!! Trust...but Verify before putting pan on final build!!!!! My 2 cents worth 😎 Note:. my opinion is NOT referring to this gentleman's work!!! Just trying to help people build more durable proper motors. And protect their investment. 👍
@@sniperpronerfmods9811 It's not the same lol. In a 383 you're just using a crank from a 400 sbc in a 30 over 350 block. The sleeve length in the 350 and 400 is nearly identical. In a 6.0 LS or 6.2 when you increase the stroke, especially when you go up to like a 427. You're pulling the skirt of the piston out of the bore wayyy further than you are on some old ass smallblock..
I don't know if they make LS engines in the old chevy 400 4.125" bore size, but my friend built this really revvy street motor with a 4.165 bore and a 327 3.250 crank giving basically a 355 displacement. I can't remember what cam he had in it, just that it was a solid roller - but that thing used to rev like a Nascar engine and people at street meets commented all the time about how much they liked how it sounded!! I'd like to recreate it someday, I see Speedmaster does a Gen I block in either 4" or 4.125" bore, might be tempted to grab one for a future build..
This is the newest video I could find and watching it a second time. How often do you make these? This is the most I've learned in a short time about the LS engine, love it.
I appreciate the engineering details! I would love going even more in depth into the engineering aspects (materials science, thermodynamics, etc...) of some of these key parts. For example, quantitative comparisons of the elasticity of various alloys composing pistons. Thank you sir!
All Pro LS heads are known for their vane on the intake guide as well. I've talked to cylinder head porters about this and it seems the room is divided on it. Some bias the floor of the ssr and some use the vane. Some use a combination of both. I am a solid roller purist as I design cams for a living, but Johnson makes one hell of a hydraulic roller lifter that under .700" lift will run side by side with a solid roller.
@@mikekojima9761 My Bad, I Knew You Were Heavily Involved With His FD Program, And His Road Racing! Keep The Videos & Information Coming! And Chris's Custom Twin Turbo Set Up On The LS In Dai's FD Car Is So Clean, And Perfect.
My perfect engine would be a 600-650hp N/A LS3 block, lightened flywheel, balanced crank, dry sump, titanium rods, cam not too lumpy, revs to 8500 and run on pump fuel. Don't know if that would work but that's what I'd like.
You can do it, but definitely make sure your valvetrain is good for it. 8500 rpms isn't a small amount, and if your valvetrain isn't up to par or if your rotating assembly isn't balanced well or isn't strong enough, your engine will end up dying very quickly. Another big thing to consider is piston travel speed. The longer your stroke is, the faster your piston travels in the cylinder. The reason for this is, at any given rpm, with a larger stroke your piston has to travel further in each of its strokes meaning it travels faster for every rpm than it would if it had a shorter stroke. This puts more stress on the pistons at the wrist pins and the rods at the journals because the piston is traveling faster and has to come at an abrupt stop quicker. You can overcome a lot of the cost of bulletproofing everything else by having a shorter stroke. You will lose some torque, but it will help you rev higher for you to build off that horsepower.
I would enjoy working with/for this guy, seems to have valuable info and knowledge. My current shop is full of rude employees and a bad owner.. can't wait to break off on my own.
it sure sounds like it just sayin AND, we NEED more people like Mike online to give all OF us LS lovers MORE online knowledge they just don't want us to know today!
I’ve been telling my wife this for years now! 4 inch stroke is really where it’s at!
Yes, but does your .... car ... have a 20 inch piston circumference ?

@@mikekojima9761 My Bad, I Knew You Were Heavily Involved With His FD Program, And His Road Racing! Keep The Videos & Information Coming! And Chris's Custom Twin Turbo Set Up On The LS In Dai's FD Car Is So Clean, And Perfect.
@@GlobalMediaInc actually it's a big single turbo, not a twin!
@@mikekojima9761 Was It Ever A Twin Setup? Maybe Early On?
@@GlobalMediaInc no never!
Great Information..Need motor on The LS 6.0 liter motors .
Old schoolers will remember this guy from SCC when he had the 300ZX
@Rogue Mentality only children who were 8 back then.....kiddo
I still have mountains of old SCC mags. It's were I also learned about the "Dave" point.
He still has that car!
I love how happy this guy is about the LS 😁
My perfect engine would be a 600-650hp N/A LS3 block, lightened flywheel, balanced crank, dry sump, titanium rods, cam not too lumpy, revs to 8500 and run on pump fuel. Don't know if that would work but that's what I'd like.
Is this a 6.0 or 6.2
@@lsxdee ls3 is a 6.2
@@jaimedeoliveira9216 thanks bro 💯
You can do it, but definitely make sure your valvetrain is good for it. 8500 rpms isn't a small amount, and if your valvetrain isn't up to par or if your rotating assembly isn't balanced well or isn't strong enough, your engine will end up dying very quickly. Another big thing to consider is piston travel speed. The longer your stroke is, the faster your piston travels in the cylinder. The reason for this is, at any given rpm, with a larger stroke your piston has to travel further in each of its strokes meaning it travels faster for every rpm than it would if it had a shorter stroke. This puts more stress on the pistons at the wrist pins and the rods at the journals because the piston is traveling faster and has to come at an abrupt stop quicker. You can overcome a lot of the cost of bulletproofing everything else by having a shorter stroke. You will lose some torque, but it will help you rev higher for you to build off that horsepower.
Happiest engine builder in the planet!! 💪🏻💪🏻
Man, I learned a lot. Great presentation.
thank you!
I would enjoy working with/for this guy, seems to have valuable info and knowledge. My current shop is full of rude employees and a bad owner.. can't wait to break off on my own.
Very good, informative video! Will order my street stroker from your company!
The intro is great and the material is amazing
This guy has forgotten more about engines than I will ever know. I would love to sweep up after him for a couple months just to learn.
His smile is contagious. This man knows his stuff.
Keep the videos coming, Mike!
THE MOST IMPRESSIVE TUTORIAL I HAVE WATCHED I WANT ONE
This man knows his shit 👍
it sure sounds like it just sayin AND, we NEED more people like Mike online to give all OF us LS lovers MORE online knowledge they just don't want us to know today!
I am going to start saving up and buying the parts you recommended for my Pontiac G8 gt with the 6.0L
