All rights reserved. More on this:. When it comes to V8 engines, gearheads appreciate this type of motor for its fairly compact layout, tremendous performance, and the noise it produces. The first engine to be built in a V8 configuration started life as a patent in First produced inthe so-called Antoinette V8 was installed in various aircraft and speedboats.

A year after the first-ever V8 engine came into the world, Rolls-Royce developed a 3, cc cu. V8 powerplant. Only three cars were equipped with this eight-cylinder lump before the British luxury manufacturer reverted to a straight-6 design. All told, Cadillac was the first automaker to mass-produce the V8 engine. Introduced inthe Cadillac Type 51 L-head V8 produced 70 horsepower from a displacement of 5.

It was Ford who did that when it introduced a V8 in its engine lineup. By the s, the V8 became the most popular engine choice in the United States, with the height of their popularity being in the s, right before the oil crisis came on the scene. To this day, motors with eight cylinders arranged in a V are the go-to configuration for most domestic automobiles.

Whereas these go-faster machines were animated by the aluminum version of the LS1, trucks and SUVs used the iron-block version of the motor. Similar to the previous-gen small-block V8, the LS1 eight-cylinder mill displaces 5. Differences over the Gen III include cast-in provisions for fuel-saving cylinder deactivation technology and updated camshaft sensing.

As for the cast aluminum engines, the GM LS family comes in 5. These include the 4. LS1 and LS6 Produced between the and model years, the 5. Whereas the LS1 and LS6 share the 5. LS2 V8 engine. First seen under the hood of the model year Corvette, the LS3 brought horsepower to the table from 6.

At the time, the LS3 was the most powerful base Corvette engine ever. As for the L99 variant, this fuel-efficient motor is standard on the Camaro SS automatic and its selling point is the Active Fuel Management cylinder deactivation system. LS4 Oh, where do we start with the LS4? Commonly labeled as the most intriguing engine of the LS family, the LS4 is a 5. Its 7-liter cu. To cope with the 4. Hand-built at the GM Performance Build Center in Wixom, Michigan, the LS7 Vee-Eight blunderbuss was good for horsepower when it was new thanks to go-faster components, such as competition-proven heads, titanium rods, and titanium intake valves.

The 6. Components that made this output possible include a 2. Latest car models:. You will only receive our top stories, typically no more than 5 per day yes no.Article may contain affiliate links. As an Amazon Associate I earn from qualifying purchases. This engine had a displacement of 5.

The design was changed to the point that the aluminum block LS1 was close in strength to the cast iron versions of its predecessor. Overall, the LS1 was in production from until There were several features of the LS1 that made it unique and began to revolutionize the small block engine.

In addition to the enhanced block strength, there are several other unique features introduced with the LS1.

This name was given based on the shape on the intake port area. Another major enhancement to its predecessor was replacing distributor ignition system with a coil near plug ignition system. While the LS1 is no longer in normal production, there are many car enthusiasts who continue to use the LS1, or some variation thereof, to build a strong engine with great performance.

One feature that makes all LS engines popular for project cars is the interchangeability of the different parts. It is very likely that if you see someone rebuilding an LS engine, it is at least partially a LS1.

The horsepower rating for LS1 varied greatly depending on the specific car model that the engine came in. In the power and torque were increased slightly to horsepower at RPM and lb-ft of torque at RPM. The LS1 engine is 5. This is only slightly smaller than its predecessor which came in at cubic incheswhich was also rounded off to 5.

The LS1 was designed with a bore of 3. This bore of 3. The LS1 engine is constructed using aluminum block and cylinder head. As mentioned previously, the new block design offered great strength despite its aluminum construction.

Designers can use the most exotic materials and likely gain improvements, although at great cost, but it is important to have the most robust design possible to take full advantage of the materials being selected. The valve architecture uses 2 valves, 1 intake and 1 exhaust per cylinder.

The LS1 engine was truly a big step for the small block V8 engine. Improved block strength and elimination of the distributor ignition system were just two of the major changes introduced with this engine.

Many backyard mechanics are still building these engines and using them to show off this powerful engine in their project car of choice.

LS1 Engine Specs Article may contain affiliate links.The LS family is a series of engines that are actually really similar to each other.

The main difference between the engines in the LS family is the displacement, intake, camshaft, and various small details. The LS1 and the LS2 have a lot in common.

But, the most obvious difference between the two is the displacement. The LS1 has a displacement of 5. This increase in displacement makes the LS2 a little more torque than the LS1. But what about the other differences? Which one is actually the better engine of the two? Arguably the best parts of the LS engine family are the awesome cylinder heads. Why is this one of the best parts? Because since the whole LS family is so similar, heads can be swapped around for your desired combination.

But what about the LS1? Well, the LS2 and the LS1 share a lot in common. The LS2 also has a slightly smaller combustion chamber, which increases the compression ratio. All of these things combined make the LS2 head better than the LS1 head. There are of course aftermarket cylinder heads for both the LS1 and LS2. Porting and polishing either of these cylinder heads will result in ridiculous amounts of horsepower. One of the main differences between the LS1 and the LS2 is in the intake manifold.

The LS2 intake is slightly better than the LS1 intake. How is it better? The LS2 intake has a larger opening and larger intake runners. The LS1 intake is designed for a 5. The later model LS1 came with an LS2 intake, which improved horsepower. Torque remains virtually unchanged. The LS6 intake, which is essentially a revised version of the LS2 intake typically makes about 4 horsepower more than the LS2 intake. Chances are you first heard about the LS1 engine, and learned about the rest of the LS family over time.

Why is it that most of us hear about the LS1 before any other LS? Why is it the most popular? Well, it was the first of the LS family. When Chevy launched the LS family it was a major game changer in the automotive world. It became the new base Corvette engine, as well as being an optional engine for the Pontiac GTO. Because of this, the LS2 was also produced in smaller numbers.

This makes it hard to find one and also makes it more expensive. You can get an LM7 out of a Tahoe which is basically just a 5. Basically, the LS2 is always going to be more expensive to buy than an LS1. All performance signs point to the fact that the LS2 makes more power.Display Options.

To keep this from becoming a blog of epic proportions, we are just going to look at the car based LS engines since those are the most popular for every-day performance. These engines are very similar in that they both share a 5. Most of the engines have the sodium filled valves that were also used along side a higher lift camshaft to up the power over the LS1. But that is all from the factory. The aftermarket groups these engines together and because they are so similar, power output is very similar.

If you must have an early LS due to budget, and you plan to keep things OE — such as the cam and intake manifold, then go with the LS6. But if you own an LS1, than finding a used LS6 to swap in or pull parts from might not be a bad idea.

Just remember, there is no substitute for aftermarket parts. Gen IV Engines. Yup, it is sitting the wrong way in the engine bay. LS4 you ask? Oh yes there is one such engine, and it is the red headed step child of all the LS engines. This engine was developed for use in front wheel drive vehicles. Its block design is shared with the Vortec engine of the same displacement, but is cast from aluminum. Not too much aftermarket development has been done with these engine as the platforms they were offered in never really were geared toward performance.

The LS2 is the 6. But there is no replacement for displacement, which is the reason the LS2 was rated at a higher horsepower. This engine even had a less aggressive camshaft and depending on where it came from power was usually around — hp.

The number is what was found in the GTOs and Corvettes, while the hp number is for the ones that came from the trucks due to the different intake manifold. Although the trucks had much more torque at lower RPM as a result. But because all of that technology is in the heads, they had to be completely redesigned.

GM worked with their Holden division on this engine and decided to make their changes with the biggest being the port design. The LS2 uses a cathedral port, while the L76 has a square port. The square port allows for more airflow which means more power.

LS1, LSA, LSX: What is the Difference?

This engine is only offered in America in the G8 GT, so you wont see to many of these except in the G8s, but the head design is very popular in the aftermarket. Because the Holden cars do not use the Active Fuel Management, they decided to take the L76 and strip all the components designed into the engine off — which spawned the L This engine is the same as the L76, but the heads do not feature all the components necessary for Active Fuel Management.

This engine was never sold in the US but it does however have the square port design that have become a popular design for aftermarket companies to use when casting their own heads. The LS3 block is very similar to the LS2. It does however have a slightly larger displacement increased to 6. While the head design is the same as the L92, it is what is inside them that counts.

GM fills these with hollow stem valves that are a larger diameter than the LS2 for more performance. This is also engine found in the Camaro SS. The LS7 is the largest engine offered in the LS street production line up currently at cubic inches.

This engine shares little with the other Gen IV engine other the basic design. Everything about the bottom end of the engine is light: light weight rods, pistons, and even the crank is lightened, all for better NA performance. The list goes on from there as this engine has a strong history in racing and a lot of technology. I mean the engines are even all hand build.A new generation of hot rodders and racers alike have taken the reigns and with that change comes a new "favorite" for engine swaps.

New Product. Part PSLSFor those lucky enough to have the LS1 in their cars, the blocks were made of aluminum, while the truck and van versions were cast iron. Other than the displacement 5. The LS was originally intended and designed as an alloy block. To add strength, engineers created a deep skirt block where the pan rail extends below the bottom of the 4-bolt main caps using a pair of 8mm horizontal bolts to laterally locate each main cap.

Other major changes included:. Topping off the engine is a thermoplastic composite intake manifold intended to reduce weight and lower inlet air temperatures. Furthermore, with the removal of the distributor, the ignition is now controlled by the ECU, firing a set of eight coils mounted near the spark plugs. When the LS1 was introduced in the C5 Corvetteit was rated at hp kW at 5, rpm and lb-ft Nm at 4, rpm. After further improvements to the intake and exhaust manifolds inthe rating increased to hp kW and lb-ft Nm.

The LS6 shares its basic block architecture with the LS1 engine, but other changes were made to the design, such as:. There were four main displacements of LS engines, 4, cc With cylinder bore size between 96 mm 3. The 4.

The first common issue with the LS1 is oil windage issues resulting in oil starvation and a list of trickle down issues to hydraulic lifters followed by camshaft bearings, valve springs, rocker bearings, and timing chain tensioners in the earlier versions of the LS1. The one thing that GM did correctly right out of the gate was the design of the cylinder heads on the LS1 engine- they were easily the best flowing and least costly option available to hot rodders; it took the aftermarket well over 5 years to develop something as high-flowing as the stock LS1 heads.

Since the LS based engines have a compact package and known for making reliable power, many small brand manufacturers have adopted this GM motor in some very interesting vehicles. Probably the most recognizable vehicle to use an LS based motor is the Hennessey Venom GTwith a pair of twin turbos on the ci LSX motor, it produces north of hp and holds the Guinness World Record for fastest accelerating production car ever, sprinting to mph in Adding to the list of niche brand manufactures using an LS based motor as the beating heart would be SSC Ultimate Aero TTwhich prior to the arrival of the Bugatti Veyron and Hennessey Venom GT held the title of the fastest production vehicle from until clocking Share Tweet.
