GM Performance Parts� CT350 delivers 350 horsepower from a classic
350 cubic-inch combination. It�s just the thing budget-conscious racers can
depend on for competitive performance and low-maintenance durability.
The CT350 is based on the popular 350 HO high-performance street
crate engine, including a stout four-bolt-main block and Vortec-style iron
cylinder heads. The Vortec heads and unique dual-pattern camshaft help
deliver more than 300 lb.-ft. of torque at 2,000 rpm and hold it above
that mark through 5,500 rpm � it peaks at 390 lb.-ft. at 3,800 rpm. With
that much pulling power, you can hold a gear longer, keeping the engine
in its sweet spot for quicker laps.
We complete the CT350 with an 8-quart circle track racing oil pan,
balancer, HEI distributor and an aluminum high-rise, dual-plane intake
manifold. Add your carburetor, starter, spark plugs, wires and water
pump � all available at gmperformanceparts.com � and you�ll be ready to

If you're going to put a big block in your project car, why not add some aluminum heads into the mix? GM Performance Parts took the venerable 454 HO, swapped the cast iron production heads for a set of oval-port aluminum castings, ands created the ZZ454. Not only do the aluminum cylinder heads flow more air, but you also drop almost 100 pounds off the nose of your car - dramatically improving performance.
The aluminum heads of the ZZ454/440 account for 15 horse improvement over the iron-headed 454 HO. These oval-port aluminum heads use huge 2.25" intake and 1.88" exhaust valves as well as small combustion chambers to add to the efficiency of the 454" big-block. The bottom end includes a Gen VI four-bolt, a forged steel crank, forged connecting rods, and forged pistons. A roller camshaft with a .510/.540" lift specs deliver a big-block loping idle as well as add to the high performance punch of the entire crate engine.
The ZZ454/440 is delivered as a complete assembly including water pump, balancer, intake manifold, and 14" automatic transmission flexplate. All you need to do is add your carburetor, ignition, and starter to complete the project.

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 809-88958733) 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.

own high-performance big-block. That's why GM Performance Parts offers
the entire ZZ502 engine as a kit. Every past is engineered to work
together to deliver 502 horses! Kit includes aluminum oval-port heads,
forged steel crank and rods, and forged aluminum pistons. It also
includes a hydraulic roller cam, valve train and valve covers. All you
will need to add is an intake manifold, carburetor, water pump,
distributor and spark plug wires.

in this carbureted combo!
By combining traditional carbureted aspiration with the high-tech
attributesof the LS platform, we�ve developed the ultimate modern engine
for your vintage car or truck�or race car.
It�s the LS376/515!
With the LS3 engine as its foundation, the LS376/515 crate engine uses
the regular-production bottom end, including an aluminum block with
six-bolt cross-bolted main caps, a Corvette oil pan and LS3 cylinder
heads with high-flow, rectangular-port intake passages. To that, we swap
the fuel injection system for a high-rise intake manifold of our own
design, a 770-cfm carburetor (sold separately) and our race-tested ASA
Hot Cam, P/N 12480110.
The new combination is worth 515 horsepower at a stellar 6500 rpm and
469 lb-ft of grin-inducing torque at 5000 rpm. Compared to the
regular-production LS3 and even our LS3-based LS376/480 crate engine,
the ASA Hot Cam gives this combination much more camshaft duration to
hold open the valves longer. It�s a horsepower-building camshaft
designed for the wide-open, high-rpm world of circle track racing and it
means big power for this great crate engine�whether it�s used on the
street or track.

GM Performance Parts� CT525 6.2L crate engine is based on the latest-
generation �LS� engine family and delivers serious power for serious
racing series, including Super Late Model and similar. It is rated at 525
hp and 471 lb.-ft. of torque!
This 6.2L engine is similar to the LS3 V-8 that is standard in the
Chevrolet Corvette, but we�ve adapted it to Circle Track racing with a
carburetor intake manifold, 8-quart racing oil pan and more. The engine
is lightweight and strong, using an aluminum block with cross-bolted
6-bolt main caps and high-flow LS3 rectangular-port cylinder heads.
The CT525 6.2L comes with coil-on-plug ignition, a water pump,
exhaust manifolds and an SFI-certified balancer. It also comes with a
14-inch/168-tooth automatic transmission flexplate. All that�s needed
to complete the assembly is a carburetor, starter and our LSX ignition
controller P/N 19171130. All the necessary parts are available online at
gmperformanceparts.com.

Between 1967 and 1969, the legendary L88 was the ultimate expression
of Chevy�s Big-Block power, combining a rigid iron cylinder block with
lightweight aluminum cylinder heads and a single four-barrel carburetor.
That raspy rat engine was rated at 480 horsepower, although the figure
was generally thought to be on the conservative side.
GM Performance Parts has recreated that classic Big-Block combination
in the ZZ427/480 � including the 480 horsepower rating (and it just might
be a little on the conservative side, too). Like the original, it features a
forged steel crankshaft and high-flow, oval-port aluminum cylinder heads.
We�ve upgraded the camshaft from the original�s mechanical flat-tappet
design to a smoother hydraulic roller, which delivers great drivability
characteristics and a broader rev range. A 10.1:1 compression ratio
means it will perform great on pump gas, too.
Whether you�re building a �69 COPO Camaro resto-mod tribute, a
modified mid-year Corvette or a street-tire class winner, the ZZ427/480 is
the heritage-inspired crate engine that delivers the performance that built
the Big-Block�s legendary reputation.

One of the most legendary engines in muscle car history was the
Chevy 454 Big-Block. With the tall-deck 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.
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, 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.

The Ram Jet 502 blends the legendary torque and performance of the
Big-Block with a modern port fuel injection system and tunnel ram-style
high-rise intake manifold. It�s a combination that offers uncompromising
performance in a visually stunning presentation.
The unique Ram Jet fuel injection system stands 11 inches tall at its
highest point and consists of a two-piece manifold/plenum assembly,
eight injectors, a throttle body, and an updated MEFI 4 controller. Setup
instructions are included, making it a simple, �plug-and-play� installation.
Supporting the unique induction system is a robust bottom end with
an all-forged rotating assembly and a smooth hydraulic roller camshaft.
The heads are GMPP�s high-flow aluminum oval-port parts.
You�ll need to check your ride for clearance before closing the hood over
the Ram Jet 502. Then again, it looks so impressive, you may just want
to cruise around with the hood off!

The LS7 is the standard engine in the Corvette Z06 and its 7.0L displacement (427 cubic inches) makes it the largest small block engine offered in a production car. Unlike LS1/LS6 engines, the LS7 uses a siamesebore 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. LS7 engines are built by hand at the GM Performance Build Center in Wixom, Mich.

A 10-second car is quick, but the ZZ572/720R could achieve that with a
couple of its spark plugs left in the pits. It is the king of all Rat engines
and is capable of pulling your bracket racer or heads-up challenger down
the 1320 in the 9-second range.
The ZZ572/720R�s true value lies in its ready-to-run status when
delivered. Rather than waiting weeks for a racing engine shop to build
a custom combination, we deliver the ZZ572/720R fully assembled;
just bolt on the included Dominator-style 1150-cfm carburetor, along
with a starter and fuel pump (not included) and you�re ready to go.
The ZZ572/720R is built with the best stuff we can find, including an
all-forged rotating assembly, rectangular-port aluminum cylinder heads
with 113cc intake ports and 2.25/1.88-inch valves. There�s also a solid
roller camshaft with 0.714/0.714-inch lift.
If you�re building the ultimate dual-purpose car, the ZZ572/720R is
suitable for limited forays on the street. It has a 12.0:1 compression
ratio, so make sure you�ve got access to 110-octane gasoline before
hitting the local cruise night!

More than 550 supercharged horse-power with exceptional refinement!
The Cadillac CTS-V�s 6.2L supercharged LSA engine delivers 556
horsepower with refinement that is rare in the world of high
performance. It is smooth, quiet and well-balanced � all while
delivering breathtaking power.
A unique aluminum cylinder block casting houses a forged steel
crankshaft and super-tough reciprocating parts, integrated piston-cooling
oil jets and high-flow cylinder heads that support the airflow enabled by
a 1.9L, sixth-generation supercharger with four-lobe, high-twist rotors.
The advanced rotor design broadens the supercharger�s effective range,
enhancing low-rpm torque and high-rpm horsepower.
GMPP�s LSA 6.2L supercharged crate engine package comes fully
dressed, from the top of the charge-cooled supercharger assembly to
the ignition system, water pump, balancer and more. It is a less-costly
alternative to the LS9 engine and makes a great transplant for any off-
road LS-powered vehicle or pre-1979 car or truck. It also comes with
conventional wet-sump lubrication system.

It helps propel the 3,324-pound ZR1 from 0-60 in 3.4 seconds and through the quarter-mile in an astonishing 11.3 seconds at 131 mph�all the way to a top speed of 205 mph!
Those stats make the ZR1 not only the most powerful car ever from GM, but the quickest and fastest, too!
GM Performance Parts is thrilled to offer the LS9 6.2L in a fully dressed crate engine package. And while it shares the 6.2L displacement of other LS engines, this one is unique, with stronger block casting, stronger cylinderhead castings and steel cylinder liners that are honed with a deck plate installed to maximize performance and cylinder sealing.
High-rpm-validated lightweight reciprocating parts, including titanium intake valves and connecting rods, are used along with high-flow cylinder heads that flow the charge forced on them by a sixth-generation supercharger.
A revised, higher-helix design delivers greater power at the low end and sustains it longer through the rpm band for broad, on-demand power whether off-idle or at speed.
