Product images may differ from actual product appearance.
Power your project with the next level
of crate-engine convenience, assurance
When it comes to performance innovations that save time, money and
guesswork, Chevrolet Performance once again leads the way!
Chevrolet Performance pioneered the concept of crate engines more than
four decades ago, and continues to lead the industry with our unprecedented
Connect & Cruise crate powertrain systems - factory-engineered engine and transmission
combinations that include all the electronic control modules,
wiring harnesses and other key components.
Three Connect & Cruise systems are offered, including the all-new
5.3L/4L65-E kit, with 320 horsepower, the Corvette-derived 430-hp LS3 paired with a 4L65-E four-speed transmission, or the 556-hp supercharged LSA engine, which
is matched with the 4L85-E transmission (*4L85-E is reman in 2013)
Chevrolet Performance engineers matched the engines and transmissions for
optimal performance and durability, so you can wring out every horsepower
from them with total confidence! The specially calibrated controllers are
designed for retrofit installations in older vehicles, for easier and quicker
installation and operation without the need for third-party tuning.
The convenience of a crate engine, the assurance of factory validate
performance and the value of an inclusive package
- that's what you get with Chevrolet Performance's Connect
& Cruise crate powertrain systems.
Each kit delivers a brand-new, fully assembled crate engine,
a brand-new or remanufactured electronically controlled
overdrive transmission, electronic control modules for both,
and the engine control hardware to get it all running in your
project vehicle - including the mass airflow sensor, oxygen
sensors and even the special throttle pedal for the engines'
electronic throttle bodies.
Chevrolet Performance engineers matched the engines with
their respective transmissions, ensuring they are up to the
task of channeling big power with absolute dependability.
The engine controller is specially calibrated to run the engine
without some of the production-vehicle features that aren't
required in an older vehicle. That means no ''trouble'' codes
and no need for third-party tuning. Better still, the systems'
unique SuperMatic transmission controllers are designed to
work with the engine controllers for a seamless, ''plug and
play'' installation that is quick, easy and intuitive. Detailed
instructions outline all the necessary steps.
The engineers did all the hard work of designing and
calibrating perfectly matched powertrain systems - and
they covered them with a 24-month/50,000-mile limited
All you have to do is install them and start cruising!
LC9 327ci Engine
The 5.3L engine shares the same displacement as the original 327-cubic-inch Small-Block
of the 1960s, making it a great choice for customers who want a 21st-century edition of the
327 for a resto-mod vintage Chevy II or mid-year Corvette. It is rated at 320 horsepower, and
because the 5.3L engine was originally engineered for truck applications, it offers a broad, flat
torque curve that's ideal for giving older trucks and full-size hot rods an excellent feeling of
low-end performance. It makes 300 lb.-ft. by only 2,000 rpm and holds above that level all the
way to 5,500 rpm. It peaks at 4,400 rpm with 335 lb.-ft.
Engine Control Modules and Harnesses
A precisely calibrated engine control module is essential to making your
fuel-injected LS engine perform in your older vehicle - and Chevrolet
Performance is your source for controllers that are designed for easy, ''plug-and-play'' installation and, in most applications, no need for third-party
Unlike production controllers that may or may not come with a used
engine, these controllers are calibrated for installation in older vehicles. That
means many of the features required for late-model production vehicles
are ''turned off,'' because they're not required in older cars and trucks. That
means features that may trigger a diagnostic trouble code and possibly
affect performance - requiring additional tuning - are not enabled.
These inclusive kits deliver all the components required to plug into the
engine and get it running - from the controller itself and the accompanying
wire harness to the mass airflow sensor, oxygen sensors and even a
throttle pedal assembly for engines equipped with an electronic throttle
body. The kits also include detailed instructions to help you do it right the
first time, even if you have no experience.
Most Engine Control Modules Kits Include:
Two oxygen sensors
Two oxygen sensor mounting bosses (for installation in the
A mass airflow meter
A mass airflow meter mounting boss (for installation in the
air intake system)
A throttle pedal assembly (for use with the electronically
A specific oil pressure sensor that is compatible with
the harness (when needed)
A complete wiring harness with fuse box and necessary cam
sensor and MAP sensor jumpers

Each Chevrolet Performance controller kit is a true stand-alone system.
All that's needed to get a vehicle running with it are power and ground
sources, a high-pressure fuel pump and an electric cooling fan.
Each Crate Powertrain System Includes:
Brand-new, fully assembled crate engine
SuperMatic transmission control module
Calibrated engine control module
Two oxygen sensors and mounting bosses (for installation in the exhaust system)
