Why the Chevy LS is the Best V8 Engine

Here’s an in-depth teardown and analysis on the infamous GM LS engine!
In this video, we discover one of the most popular V8 engine, the GM LS series, which debuted in the mid 90’s and was used in many vehicles in General Motor’s lineup in the following two decades. A 4.8L LS Engine from a 2003 Chevy Silverado is completely disassembled and analyzed to find out why this engine is so popular and successful: Its small form factor, abundance and availability, cheap price, huge aftermarket support, reliability and strength.
Unlike newer overhead cam design engines, the LS managed to take the crown as one of the best V8 engines with its antiquated push-rod design. This design sets the camshaft in between the “V” of the engine, and uses individual push rods to power the valves on top the engine heads.
In this video we also examine a very neglected and sludged up engine and find out just what happens when you don’t change your oil, in addition to a few other weak spots to look out for if you are thinking of buying a vehicle with GM V8 engine, or building one to swap into your project car.

[@RemyRAD]

This guy is a true pro. This was extremely well articulated. There are no dead spots. It's a barrage of constant information. This guy is a top professional. This guy is a college professor. Of mechanical engineering. Now what I want to know is. Who would have this lovely LS, engine. To have never been giving it oil changes? I mean who does that? You want and get a high performance engine. To go with your high-performance vehicle. That means changing the oil once in a while. Though, one of my most beloved bosses. I worked for early on in my career. Who believed in me. He had a Buick Electra 225.. And in the nearly 400,000 miles he had on that car. He never once changed the oil.. He would just keep adding it. Never changing it or the filter. It was amazing! His eldest son was my/is my, older high school buddy and great friend. Like a big brother. And his dad Max. He would joke about never getting the oil changed. So I guess it really just comes down to. You win some. You lose some. With better maintenance. It might last a little longer. But then again it might not? He never changed the oil! And he had that car for over 20 years. More like 30. From the early 70s until the late 90s. I don't think they make them like that anymore. Now they are guaranteed to fail and not last. That's a much better business plan. Than making things that last. I built some tape recorders back in 1979. That are still running today. As people notified me they still had my recorders and were still using them. After all these years. It made me feel so proud.. I was the Quality Control Manager. I guess I did my job well. Mine is still like new.. Like showroom, new. No more than a couple thousand hours on the machines. Basically broken in and with new heads. And maybe one of these days before I die. I'll sell it. Maybe? I was young and pretty when I built it. Now I'm old and frail. And it still looks brand-new. It hasn't aged a bit. God dammit!!! And the name of the machine is called a Scully. Google that. Pictures of the machines you will see in the control rooms with the Beach Boys, Jimi Hendrix, Tommy James and on and on. Those were the machines! I built. But before my time with the company. That the founders built. And those were important shoes I had to fill.. So many hit records were cut on those machines. And it still to this day, boggles my mind. That I would end up the Quality Control Manager and Chief Test Engineer. I mean how did that happen? I liked using those machines, sure. I never imagined a job offer would come out of the blue air I never applied for. And I saved the reputation of the company. I thought that was pretty groovy of me. Your voiceover narrative was fabulous! That's the way to produce one! I am very impressed with your engineering prowess, sir. It's not often I run into the real deal like yourself these days. You know those engines like you know your loving partners intimate parts. And know how to keep them in tip top condition. And with their rear ends intact. Not to mention the transmission fluid of your lube. Where you want just the right pressure. Oh baby. At nothing like a nice full synthetic for the crankcase. I went fully synthetic back in 1978. As soon,, as it was offered. Mobile 1. No more sludge! It don't care what the temperature is. I won't use anything but 100% full synthetic's. And because I am an electronics guy not a mechanical guy. You pursue the state-of-the-art in lubricants. Use what the military gets. Anything less is sheer lunacy. This is the most expensive gizmo that makes you go. You feed it the best oil. Anything less is madness! I'm a fucking engineer so I know! Yeah baby! I get so excited when talking about lubricants RemyRAD

[@alexandrugajin763]

Sludge is actually dirt, carbon from the combustion, a little bit gets in the oil everytime a cylinder fires, metal shavings, so with time all these added to the oil makes it thicker, in this case so thick it stuck on the walls and due to poor cooling, oil also cools the engine. It litteraly cooked on to the interior walls of the engine. So your guess might be correct. Who ever drived this engine, does not deserve a licence drive or ever touch a car... Is just sad to see so much science go to waste.

I think there's one particular thing that makes LS engines good; they're bases off the old small block 350, and that means they're simply designed, simple to work on, parts are cheap, they're reliable and powerful.

[@fun_ghoul]

"Based on", yes, but nothing is interchangeable.

[@Connor4x4]

They're not based on the 350 at all. They share some basic architecture but nothing is interchangeable. They're still the best modern engine on the market

[@joelmacdonald6994]

@@Connor4x4 agreed. Pretty well any OHV V8 shares a basic architectural design, there’s not much to change in that regard. Just as the BBC and the SBC don’t interchange parts, same with the LS. The only real differences you’ll see is crank plane, and oil/coolant distribution.

[@FWDSUXARSE]

They were a clean sheet design. Only thing they share with the gen II SBC is connecting rod bearings and valve lifters if I'm not mistaken.

Nice video, thank you.

Other notes, be very careful with that crankshaft position sensor ring on the crank shaft, it can be bent easily, and wont run correctly if at all. Also note the roller lifters underneath the plastic lifter retainers. Those need to be removed to allow the lifters to be removed before the camshaft will slide out.

That carbon in the intake is one reason why I don’t like direct injection, with a carburetor the fuel rushing by helps clean the deposits and stops them from forming. Although running a port injected engine hard will help to break some of the deposits up.

[@speedkar99]

Yeah except this one didn't fair so well

[@ljpr360]

Great Video, definitely prefer the UR series engines(Toyota/Lexus V8s). I guess the cost of them is what holds people back from using them more commonly. These Iron block pushrods can be cheap.

[@speedkar99]

Agreed, Toyota does make reliable V8s but I think the LS can take more boost and is much cheaper

[@zukobringas5096]

That proves that simple pushrod engines can still compete and even outperform vs comparatively complicated overhead camshaft designs in terms of power, reliability and ease of maintenance. As for 4cyl engines, we can compare GM LS1 to the old Toyota 2T and 3T engine series which were also pushrod type, also powerful with huge potential and so simple and fun to work on.

Man, can you review more new vehicles? liked your vehicle reviews that focused on various mechanical components.

Ok 2 questions I have a 2012 Corvette with the ls 3 so all this sludge is coused from not changing the oil regularly? And 2 do I need a catch can even if I change my oil regularly I usually change oil and filter when the oil management system hits 50% is that often enough?? Great channel new subscriber. Thanks

Lots of advantages to a pushrod engine over an overhead cam. Simple and cheap, narrower and with a lower center of gravity, and superior low end torque to name a few. Glad to see you taking on some good ol' Detroit Iron for a change : )

Pushrod engines do not inherently have better low-end torque, and all things being equal, "narrower" would mean a higher CoG unless you're swapping in a dry sump oiling system and custom mounts.

Yes it's good to try different brands....been doing too much Honda and Nissan but that's child's play for me now

@@fun_ghoul Pushrod engines are two valves per cylinder which means smaller intake ports which promotes better fuel air mixture at low RPM. They are narrower because they don't have the cam in the head and four valves per cylinder, so the heads are not only narrower but much lighter as well. That plus the cam in the block means a lower center of gravity.

The F*rd Mod motor comes to mind... _"They are narrower because they don't have the cam in the head and four valves per cylinder, so the heads are not only narrower but much lighter as well. That plus the cam in the block means a lower center of gravity."_ This is only true if you assume that both engines have the same deck height. Needless to say, this is not the case in reality. Also, in reality, cams actuating fewer valves weigh less with fewer lobes, and the weight of the valves is similar between both engines because the 4V engine (again, rolling with your assumption) has smaller, lighter valves.
