The LS7 can be pretty expensive, but you can always buy a stroker ci kit for your LS3. Another popular stroker size is a ci LS1 stroker.
The cheapest of the LS engine family is the 5. As you can imagine, the aftermarket for the Chevy LS has exploded since its massive rise. The most common modification being a high-performance camshaft, which is really the best bang-for-buck upgrade you can do on the LS engine.
The aftermarket also makes a lot of swap kits, making it a breeze to swap a Chevy LS engine into basically any automobile you want. Chevy really knew what they were doing when they designed the LS engines, they designed a V-8 engine family that made good horsepower and good torque. How did they do this? They achieved this by using modern computer technology to test different port lengths and designed to find the best performing head design.
You may be surprised by how the port shape, size, and length can affect torque and horsepower ratings. Chevrolet also designed the intake manifold using similar technology, they aimed for the LS engine to produce usable power really low in the RPMs, and decent power up high. They also focused on small features like the cam size, they made the cam core massive, which means you can easily fit a. Some people even leave the stock heads on and just have them worked over, combined with a big cam many LS engines are making over rwhp with just head work and a cam.
What other engines can you name that makes that much horsepower with just a cam swap? Believe it or not, a 5. A Miata 1. The push-rod design that they continue to use is unlike almost all modern engines that have overhead cams.
You can achieve better performance and economy with an overhead cam but at the cost of a much larger and heavier engine. There are quite a few choices when it comes to which LS you should swap into your car. If you have the money an LS7 or LS9 are awesome options. The LS7 produces a ridiculous amount of horsepower naturally aspirated. The LS9 produces a ridiculous amount of power with its supercharger.
GM first introduced the LS family of engines in the Corvette. The LS1 engine is a 5. It also featured coil near plug ignition, and various other new engine management features. These new features made it vastly greater than the previous generation's small block. Larger heads will cause valve-to-block issues. Transplanting an LS1 could be difficult because the Vettes came with throttle by wire throttle bodies and electronics to operate them. You must have the accelerator pedal and TAC module from a Vette that match the PCM programming to use the stock throttle body.
This means the engine will not run if it is transplanted into a vehicle without the original vehicle steering column and decoder module. Painless VATS computer chips allow you to bypass the factory programming, making the wiring in your engine swap a snap. These were all great improvements for the LS engine family, making it a word-class engine. Introduced as Corvette's new base engine in , the LS2 uses a different intake manifold and a larger 90mm throttle body.
LS2 engines in and later Corvettes were equipped with a 58X crank position sensor reluctor wheel. In the LS3 was the Corvette's new base engine, producing hp 5,rpm and lb-ft 4, rpm. Other features included offset rocker arms, high flowing intake manifold, a slightly stronger block than the LS2 and larger injectors from the LS7 platform.
The LS3 also used the highly desirable L92 cylinder heads and a more aggressive camshaft and revised valvetrain. The stock LS3 is fitted with a LS6 camshaft that is modified with more intake lobe lift. LS3 engines in and later Corvettes were equipped with a 58X crank position sensor reluctor wheel. Steer clear of the LS4 as it is designed for transverse front-wheel-drive applications.
Unless you're modifying a front-wheel-drive car, the LS4 platform is of little value to hot rodders looking for an engine swap, as it's difficult using it in anything but what it originally came in.
The LS6 is basically a high output LS1 engine with better heads. Key features are its higher compression ratio, sodium-filled hollow stem valves and revised oiling system. You can NOT use heads designed for larger engines as that will cause valve-to-block interference.
The LS The bad news? You're probably not going to find one of these in your local wrecking yard. The LS7 was influenced by Corvette's Le Mans racing program and incorporated some serious race engineering in the engine's development. The block itself has larger sleeved cylinders with a longer stroke. The crankshaft and main bearing caps are forged steel for strength and the connecting rods are forged titanium with hypereutectic pistons. Heads feature Del West 2. The cylinder heads, with the larger valves, flow an incredible cfm.
LS7 blocks should be matched with heads designed for at least 4. LS7 engines in and later Corvettes were equipped with a 58X crank position sensor reluctor wheel. Good luck finding a wrecked ZR1 Corvette at the wreckers! These factory supercharged engines are based on the LS3 block. Looking for an emissions-legal motor that pumps out around horses, and will last for , miles?
If a stock supercharged LS engine just isn't enough power for you, why not go all out and get an Edelbrock Supercharged LS Crate Engine with an astounding horsepower and ft-lbs.
