$6185.00 430 HP 424 Torque
DESCRIPTION: LS3 Engine 6.2L
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.

DESCRIPTION: LS2 Engine 6.0L
A bigger, more powerful next-generation small-block from the new
Corvette! With the all-new, 400-horsepower LS2, GM has once again raised
the bar for production-based small-block V-8 performance. As the
standard engine in the 2006 Corvette, as well as the 2006 Chevy SSR and
2006 Pontiac GTO, the 6.0-liter LS2 builds on the success of the popular
LS1 V-8 engine with more displacement, power and technical innovation.
The LS2 is built on a new cylinder block, which shares much of its
design with the previous LS1 V-8 design, including a deep-skirt,
six-bolt-main block with structural oil pan. Subtle differences include
the crankcase vent moved to the top of the valley, relocated knock
sensors and the cam sensor moved to the front of the engine. The LS2?s
cylinder heads are high-flow pieces used previously on Corvette LS6
engines. High-tech features, such as an electronically controlled
throttle, make the LS2 a state-of-the-art performer. The LS2 crate
engine comes complete with a composite intake manifold, electronically
controlled 90-mm throttle body, fuel rail with injectors, balancer,
exhaust manifolds, water pump and a 14" flexplate for automatic
transmissions. It comes with a Corvette oil pan installed. The LS2 can
be adapted to older cars and street rods. |

LS-6-Specific Higher Lift Camshaft
As the intake air comes through the manifolds in greater
volume, it is important for the air to enter the combustion
chamber as quickly as possible to produce power. The LS-6 engine
has a camshaft that has higher lift lobes than the LS-1,
resulting in a 5 percent increase in airflow through the
cylinder chamber. |
LS-6-Exclusive Cylinder-Head Design
At the heart and soul of the LS-6: unique cylinder heads for
better engine breathing. Larger ports than those in the LS-1
engine also improve airflow by 10 percent. Compression ratio is
a healthy 10.5:1. |
LS-6-Mass
Airflow Sensor Design
The mass airflow sensor has been designed for enhanced
airflow, contributing to the horsepower increase over the LS-1
engine. Greater air intake means greater power output. |
LS-6-Positive Crankcase Ventilation System
Because of the LS-6’s increased performance capabilities,
changes were made to the positive crankcase ventilation (PCV)
design to improve oil control during high-speed conditions
(compared with the LS-1 PCV system). |
LS-6-Specific Engine Block
The all-aluminum LS-6 engine block has been refined to enable
higher piston speed and higher overall rpm than the Corvette
LS-1 block on which it is based. Hollow-stem intake valves and
liquid alloy exhaust valves are lightweight and designed to
maintain solid contact with the rocker arms during high-speed
operation.Engine does not include front
accessories, pumps, belts, tensioners, idlers, wiring harness,or
computer. |

505 HP 470 Torque
$12,995.00
DESCRIPTION: LS7 Crate Engine (limited supply)
The king of all Corvettes is the amazing 2006 ZO6. It
tops out at 198 mph, runs the quarter mile in 11.5 seconds at127 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.
