First featured in 1962, the 327 was found in everything from fuel-injected Corvettes to the very first Camaros. It was renowned for its high-rpm performance and surprising torque from a comparatively small-displacement V-8. Today's LS327/327 crate engine delivers on the same virtues, cranking out 327 horsepower and 347 lb-ft of torque.
It's a 5.3L LS power plant with the same 327-cubic inch displacement of the high-winding small blocks from the 1960s, but it is "breathed on" and updated by GMPP engineers with a hotter cam, Grafal-coated high-silicon pistons and more. In other words, it's perfect for re-powering your truck or dropping into your classic vehicle or street rod (check with your state or local regulatory agency for emissions regulations in your area).
When GM dared to release a redesigned small-block in 1997, it succeeded beyond the expectations of enthusiasts around the world. Known as the LS Family V-8 small-block, the first and most popular version is the high-performance LS1 –available here as a complete crate engine from GM Performance Parts. In many ways, the LS1 is superior to any small-block that came before it.
A deep-skirt, six-bolt-main block, with structural oil pan and other carefully engineered features, helps make the LS1 a strong, smooth running and dependable engine. A highlift camshaft actuating big 2.00/1.55 valves in symmetrical-port cylinder heads helps make it a uncompromised performer. The engine is rated at 350 horsepower and 365 lb.-ft. of torque. The engine includes a GTO-style oil pan, electronic drive-bywire throttle body, intake manifold, exhaust manifolds, fuel rail with injectors, balancer, and 14" automatic transmission flexplate. It makes a great performance engine for your performance vehicle project – just add your wiring and electronics.
A handy reference guide is available to help install the engine in older cars with minimal guesswork. Go high-tech with your next project! *Applications have not been validated.

Nothing says performance like engine code LS6! Producing more than 400 horsepower, the LS6 transformed the Corvette Z06 into a world-beating sports car. GM Performance Parts now offers this ultimate small-block performer in a complete crate engine package – just the extra muscle your Corvette or F-car road racer needs to sweep off the competition.
The 5.7-liter LS6 builds on the inherent strengths of the Corvette's LS1 engine, but benefits from a higher-lift camshaft and higher-compression pistons to raise horsepower from 350 to 405, and torque from 340 lb.-ft. to 400 lb.-ft. Such tremendous power is produced through the use of hollow-stem valves, a more aggressive camshaft, improved intake and higher-rate valve springs. GM Performance Parts delivers the LS6 as an all-inclusive assembly, complete with CTS-V oil pan, large-volume composite intake manifold with single-bore throttle body, and high-performance long-style exhaust manifolds.
The LS6 is also a great choice for older cars and street rods whose owners are looking for high-tech performance and fuel-injected dependability! *Applications have not been validated.

What's Hot? 430 horse · 376 cubes · 24-month GMPP warranty
Starting with the '08 Corvette, the world was first introduced to GM's latest small block V8 creation – the 6.2-liter LS3. A continuation of the industry leading V8 engines from GM Powertrain, the LS3 kicks out 430 horsepower and 424 lb.-ft. of torque. (In the Corvette, those numbers go to 436 hp and 428 lb.-ft. of torque with the optional dual mode exhaust system.) It's a brute of a small block with 376 ready cubes at your beckon call. The LS series of engines from GM Powertrain have broken new ground for efficiency and performance from a pushrod platform engine. The LS3 continues the engineering breakthroughs with revised cylinder heads featuring rectangle ports borrowed from the vaunted LS7.
The heads feature 63 cc combustion chambers, 2.16-inch intake valves, and 1.59-inch exhaust valves. The camshaft features an aggressive .551-inches of lift on the intake side with less overlap (than the LS2) for even greater airflow and power. Rocker arms with a 1.7:1 ratio sit on top of the heads. In the bottom end, the aluminum 6-bolts/main block features 4.06-inch bores and 3.62-inch stroke. A nodular iron crankshaft, powdered metal rods, and aluminum pistons (10.7:1 compression ratio) round out a rev-happy short block. Red line for the LS3 comes at 6600 rpm, and you will get there very quickly. With a high-tech GM foundation, aluminum block, and high flowing rectangular-port heads, the LS3 is the new standard in the small block world. The LS3 helps power the new Corvette to a top speed of 190 mph. What will it power you to?
What's Hot? · Bigger Cam! · Carbed intake · 24-month GMPP warranty
You know that the LS3 is the hot new small block V8 in the GM arsenal, but you still want more. We proudly offer you the LS 376/515, an upgraded LS3 that is equipped with an aggressive camshaft and GM Performance Part's exclusive carbureted intake manifold. Two simple upgrades that add up to 515 horsepower – a 115 horsepower bump over the stock LS3. To match the high flow rate of the LS3 cylinder heads, our GM Performance Parts engineers installed the "ASA Hot Cam" (p/n 12480110).
This is a hydraulic roller camshaft that offers up .525-inch intake and exhaust valve lift numbers and duration @ .05-inch of 226° intake and 236° exhaust. It truly is a "hot cam" that offers up an aggressive lope at idle and a buzz saw power band that never stops. The GM Performance Part engineers coupled that aggressive camshaft and high flowing cylinder head design with our new carbureted intake manifold specific for the L92/LS3 cylinder heads (p/n 25534401). The manifold offers a dramatic increase in horsepower and a simplified installation. If you like what you see with the new LS3, you'll love the LS 376/515. It's everything you want in a small block V8 – big power, simple package, and a big-inch foundation. The GM Performance Parts intake allows for an easy installation that you will find familiar while still being very powerful. The LS 376/515 – the next great small block from GM Performance Parts.
What's Hot? · Hot Cam! · Big EFI power · 24-month GMPP warranty
The hot new small block V8 in the GM lineup is the hyper-aggressive LS3. It offers a high-revving 376-inch combination that represents generations of small block V8 development and engineering. Not only is the LS3 an amazing engine in its stock configuration, but with those high-flowing rectangular port cylinder heads, the LS3 is loaded with potential.
To tap into this potential, the engineers at GM Performance Parts offer you the LS 376/480 – an LS3 with an upgraded camshaft that ups power by a whopping 50 horsepower! The LS 376/480 comes with the same great features as the LS3 crate engine. The bottom end includes a 6-bolt aluminum block, nodular crank, high performance rods, and 10.7:1 pistons. The heads are high-flowing rectangular-port units that share their design with the amazing LS7. The same EFI intake manifold feeds the hungry engine, while 1.7:1 roller rockers work with the upgraded camshaft. The GM Performance Parts engineers picked the LS Hot Cam (p/n 12617570) to take the LS3 to the next level. This cam specs out with .525-inch intake and exhaust valve lift. Duration (@ .050 inches) is 219° intake and 228° exhaust. This cam allows for a dramatic increase in power across the power band while still maintaining good street manners.
The engine will idle and cruise just like an LS3, but the power increase is there whenever you need it. With all of the same great components as the LS3, but with an additional 50 horsepower, the new LS 376/480 is ready, willing, and able to answer your call for a new LS crate engine.
The king of all Corvettes is the amazing 2006 ZO6. It tops out at 198 mph, runs the quarter mile in 11.5 seconds at 127 mph, and hits 60 mph in a jaw-dropping 3.5 seconds (in first gear). All of that performance is the result of superior GM engineering and an engine we call the LS7 –the most technologically-advanced small-block ever built. A natural continuation of the LS Family, the LS7 uses a 7.0-liter aluminum dry-sump block, CNC-ported cylinder heads, and titanium rods and valves to pump out 505 hp and 470 lb.-ft. of torque.
Talk about efficient –the LS7 helps the 2006 ZO6 get over 28 mpg while still being the fastest Corvette ever produced! Is this the Chevy small-block in its highest form? Only you can decide, and GM Performance Parts has made it that much easier by offering the already legendary LS7 as a complete crate engine, ready to bolt into your favorite project car. *Applications have not been validated.

A perfect marriage. Based on the potent LS9, the LSA has a slightly smaller supercharger and a few other unique components designed to deliver Cadillac's signature quietness and refinement. But make no mistake; this is one powerful performer.
Some of its high-performance credentials include: a unique aluminum-cylinder block casting that houses a forged steel crankshaft, integrated piston cooling oil jets, high-flow cylinder heads and relatively mild camshaft. And unlike the LS9, the LSA comes with a conventional wet-sump lubrication system. With its 556 horsepower and 551 lb-ft of torque, along with excellent idle quality and "right-now" throttle response, imagine how this engine could transform your Z28 Camaro or C6 Vette!
With the 6.2L SC thundering under the hood, the 2009 Corvette ZR1 is not only the most powerful car ever from GM, but the quickest and fastest, too! In fact, it takes only a mere 3.4 sec. for ZR1 to reach 60 mph. And now, you can order GMPP's fully-dressed LS9 crate engine package for your own project car. And while it shares the 6.2L displacement of other LS engines, this one is unique, with stronger block casting, stronger cylinder head castings and steel cylinder liners that are honed with a deck plate installed to maximize performance and cylinder sealing. The LS9 SC is a great choice when you want to build your own ZR1 or that potent '69 Camaro you've only dreamt of before.
That's what you get with the new LSX376. GM Performance Parts takes the economical LSX Bowtie standard-deck block, adds blower-friendly 9.0:1 forged pistons and combines them with the LS3's high-flow heads to create an affordable foundation for supercharged and turbocharged combinations. We deliver the LSX376 without an intake manifold and other accessories to keep the price lower and enable the installer to tailor the induction system to suit the blower or turbo system.
Swap in the LSX376 in a vehicle originally equipped with an LS engine to give it a stronger bottom end for forced induction, or swap it into a street rod or classic muscle car body for a modern update. Our baseline horsepower and torque ratings are based on testing with the production-style, normally aspirated injection system. There's no telling how much power you can realize with a carefully tuned turbo or supercharger system! See page 286 for information on our reference guide P/N 88959384 for installing an LS engine in an older car. NOTE: Due to the number of application variations, the LSX376 crate engine does not include an oil pan. See the LS Engine Components section for production-style oil pan choices. Also, the LSX376 valve covers do not include provisions for mounting the ignition coil brackets. Aftermarket or custom relocation brackets must be sourced.
One of the most legendary engines in muscle car history is the Chevy 454 Big-Block. With the LSX Bowtie block, GM Performance Parts engineers were able to build a 21st century 454 with the latest technology - and it requires no more space under the hood than a production LS engine. It's perfect as the power plant for a late-model Camaro drag car or a high-tech retro-fit for a '70 Chevelle pro-touring machine. The LSX454 is filled with an all-forged, super-tough rotating assembly and features a pair of our new, deep-breathing LSX six-bolt cylinder heads. It also comes dressed with great-looking, all-new orange powder-coated valve covers with engraved "LSX454" logos.
GMPP delivers the LSX454 without an intake manifold and other accessories. With a carburetor and high-flow GM Performance Parts intake manifold, the LSX454 is good for about 620 horsepower and 600 lb-ft of torque or about 580 hp and 600 lb-ft. with fuel injection. See page 286 for information on our reference guide P/N 88959384 for installing an LS engine in an older car. NOTE: Due to the number of application variations, the LSX454 crate engine does not include an oil pan. See the LS Engine Components section for production-style oil pan choices. Also, the LSX454 valve covers do not include provisions for mounting the ignition coil brackets. Aftermarket or custom relocation brackets must be sourced.
