LS3 -Introduced on the 2008 Corvette, the LS3 brought LS base performance to an unprecedented level: 430 horsepower from 6.2L (376 cu in) – making it the most powerful base Corvette engine in history. The LS3 block not only has larger bores than the LS2, but a strengthened casting to support more powerful 6.2L engines, including the LS9 supercharged engine of the Corvette ZR1.
LS7 - A legend in its own time. The LS7 was the standard engine in the C6 Corvette Z06 and its 7.0L displacement (427 cubic inches) makes it the largest LS engine offered in a production car. Unlike LS1/LS6 engines, the LS7 uses a Siamese bore cylinder block design – required for its big, 4.125-inch bores. Competition proven heads and lightweight components, such as titanium rods and intake valves, make the LS7 a street-tuned racing engine, with 505 horsepower.
LS9 - The most powerful production engine ever from GM, the LS9 is the 6.2L supercharged and charge-cooled engine of the Corvette ZR1. It is rated at an astonishing 638 horsepower. The LS9 uses the strengthened 6.2L block with stronger, roto-cast cylinder heads and a sixth-generation 2.3L Roots-type supercharger. Like the LS7, it uses a dry-sump oiling system. It is the ultimate production LS engine.
Small Block Engines.
Nobody Knows Small-Blocks Like Chevrolet Performance Led by legendary engineer Zora Arkus-Duntov in the 1950s, Chevrolet Performance engineers wrote the book on Small-Block performance and have been continually refining it for nearly 60 years.
New cylinder heads and valvetrain components help make some of our Small-Block crate engines better performers and stronger values for builders looking for a ready-to-install engine. Chevrolet Performance’s lineup is also unmatched in the industry, with a range of crate engines for every project, from our 350/290 Deluxe budget performer to our classic ZZ4, all new ZZ5 and an enhanced ZZ383 stroker engine!
And if you’re a circle track racer, our sealed crate engines deliver the power you need to win, with the dependability you can count on.
All of our Small-Block crate engines are built with brand new parts, from the cylinder block and rotating assembly to the heads and all the supporting accessories. The blocks feature durable four-bolt main caps, too, which you won’t find in many salvage yard core engines. Best of all, the non-racing engines are backed by a 24-month/50,000-mile warranty for worry-free performance.
Big Block Engines.
For half a century, Chevrolet’s big-block engines have set the bar for big torque and the power that comes with it – whether you’re hauling down the drag strip in a 9-second Camaro or hauling that Camaro to the drag strip in your truck. Chevrolet Performance is the only source for brand-new big block crate engines built with brand-new parts – and each is built with the latest cylinder block casting, which is stronger in many key ways to previous production engines. Save yourself the trouble of rebuilding or even finding a good, rebuildable core.
Our lineup of assembled, ready-to-install engines offers something for every budget and project – and you’ll be on the road quicker, with little or no time required for fine-tuning. Use our classic 454 HO for your classic cruiser, our 502 HO to re-power your truck for great towing capability. Our 427 crate engines make great additions to classic Corvettes and COPO Camaro tributes, while racing engines like the ZZ572/720R arm your drag racer with formidable firepower!
When you need big torque, look no further. Nobody knows big-blocks like Chevrolet Performance!
Chevrolet Performance’s LSX crate engines take LS power to the next level, with racing-engineered combinations that deliver power with strength. Each is based on the high-performance LSX Bowtie block, which is designed to support extreme performance combinations, including supercharging, turbocharging and nitrous.
Chevrolet Performance’s LSX376 B-8 and LSX376 B-15 engines are specially designed for the high-pressure demands of forced induction, with forged crankshafts and pistons. Our cylinder heads complement that tough block with tremendous airflow and six-bolts-per-cylinder clamping strength that supports power adders of all types.
The LSX454R is the biggest, baddest LS engine in Chevrolet Performance’s arsenal. It’s a 750-horsepower, naturally aspirated drag strip assault weapon that’s capable of propelling your race car down the track in 9 seconds or less. If your car can handle the power, the LSX454R will help you win! When big LS power is what you need, turn to Chevrolet Performance.
