Now of your looking for that ZR1 performance GM now sells a LS9 crate engine to get you that 640 HP

Corvette ZR1 bragging rights for your project car!
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.

Or if wanting more like the Caddie has

LS pedigree. Cadillac refinement. 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!

Or how about in the LS7 footprint

Seven liters of pure troublemaker!

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.

Or for cheaper cost the LS3 with a hotcam already installed

LS3 + Hot Cam = Loads of Fun.

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.
