The LS1 model engine saw extensive use in the Corvette until 2004 and the Camaro until about 2002. eBay offers several complete engines that are designed to be ready to perform in your project or donor vehicle.
General Motors LS1 5.7L OHV V-8 General Motors LS1 5.7L OHV V-8. The winning formula for General Motors Corp.'s entirely new LS1 OHV V-8: It's the most horse-power that can be had for less than $40,000. By a long stretch.
As a starting point, the LS1 was an eye-opener for Chevy fans. Its all aluminum architecture made it significantly lighter than past GM V8s, and power was great: the engine was rated at 345-350 horses in the Corvette (depending on model year) and would check in at as much as 325 hp in the F-body cars.
The LS1 (5.7 liter, 346ci) was the engine that started it all. Given the Gen III designation and introduced in the 1997 Corvette and the Camaro/Firebird in 1998, it was a huge departure from the previous LT1 (Gen II) powerplant and included features such as a deep-skirt aluminum block and coil-near-plug ignition.
The engine family commonly called the LS series debuted in 1997. General Motors called it the Gen-III Small-Block, with the iron-block versions in trucks and the all-aluminum LS1 introduced in the then-new C5 Corvette.
Bottom line, the LS engine is compact, lightweight and very strong. Best of all, specialists like us who know it inside and out can extract a lot more power while keeping it reliable.
At Speed Week 2017, George Poteet and the Speed Demon team used that LS to run 428.784mph and this year, with a better racing surface, it ran 448.508mph, ensuring that it's the fastest LS engine in the world.
Chrysler later made the 5.7 L Hemi available in all models of the 2004 Dodge Ram, Dodge Durango, the 2005 Chrysler 300C, Dodge Magnum R/T, Jeep Grand Cherokee, the 2006 Dodge Charger R/T, Jeep Commander, the 2007 Chrysler Aspen, the 2009 Dodge Challenger R/T, and the 2022 Jeep Wagoneer.
The LS1 was used in the Corvette from 97 to 04. It was also used in 98-02 GM F-Body (Camaro & Firebird) cars with a rating of over 305–345 hp (227–257 kW), which was rumored to be conservative. The extra horsepower was claimed to come from the intake ram-air effect available in the SS and WS6 models.
To get the right parts, you need to know which version of the LS you are starting with. The easiest way to tell the difference is to check the 8th digit of the VIN code on the original vehicle.
Overview. The LS1 debuted with the C5 Corvette in 1997. This 5.7L (345ci) engine immediately promised great potential if for no other reason than it was the first Chevrolet production all-aluminum small-block V8.
When the LS1 was introduced in the C5 Corvette, it was rated at 345 hp (257 kW) at 5,600 rpm and 350 lb-ft (475 Nm) at 4,400 rpm. After further improvements to the intake and exhaust manifolds in 2001, the rating increased to 350 hp (261 kW) and 365 lb-ft (495 Nm).
Generally, Vortec engines have smaller displacements than their direct LS engine counterparts. However, both types enjoyed long production and had many variants over several decades. You can find Vortex and LS engines that share the same displacement but appeared in different years or belong to different generations.
Which is the Best LS to Turbocharge? No matter the size, all LS-based engines respond favorably to boost. In fact, even a turbo 4.8 or turbo 5.3 Vortec engine can reach power levels like those of a turbo 6.0 LS. Sure, they might need a bit more boost, but don't count them out if they're what you've got on hand.
With its dual overhead camshaft design and advanced engine management systems, the Coyote engine can offer better fuel economy compared to the LS engine. While both engines provide impressive power, those looking to prioritize fuel efficiency may find the Coyote engine to be a more suitable choice.
What is the difference between an LS1 and LS2 engine?
LS2 is designed with a 6.0L motor. Through this, it is able to flow enough air to be able to maintain 400 horsepower. For LS1, the intake is designed for a 5.7L and flows enough to keep a 350 horsepower. The latest model of the LS1 engine came with an LS2 intake, which has better horsepower.
the 5.7 and the 5.3 are actually the same motor just with different bore and stroke. Both are really fine engines and are some of the more efficient motors GM has ever produced. They are LS1 derived motors and have been proven in the field now since 1997, if not longer. Don't worry about the 5.3.
The LS7 engine is the most powerful normally aspirated engine GM has yet produced, rated at 505 HP. Also available- and with fitment in the SL-C only when ordered at the factory- is the supercharged LS9, an engine reserved for the Corvette ZR1, with 638 HP.
The aluminum blocks are not as strong as the LS-based iron-block Vortec truck engines like the LQ4 and LQ9, but both the LS1 and LS6 can be pushed to over 850 horsepower with upgraded internals. If you're on the hunt for the best mods for your LS1 engine, you're in the right place.
