Chevrolet Performance continues to lead the industry with its unprecedented Connect & Cruise crate powertrain systems - factory-engineered engine and transmission combinations. Chevy 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. Each kit delivers a brand-new, fully assembled crate engine, an electronically controlled overdrive transmission, electronic control modules for both, and the engine control hardware to get it all running in your project vehicle. The convenience of a crate engine, the assurance of factory validated performance, and the value of an inclusive package - that's what you get with Chevrolet Performance's Connect & Cruise crate powertrain systems. 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 warranty. 

LS7 7.0L, 505HP / 470TQ Engine 
Within its classic 427-cu-in displacement, engineers extracted Big-Block grunt from its high-revving Small-Block package. It features a unique, big-bore cylinder block that is anchored with a forged crankshaft, featherweight titanium connecting rods, and friction-coated pistons. But it's the airflow capability of the cavernous, CNC-ported heads that enables its tremendous power. Large-volume, straight-passage intake runners channel air directly through 2.20-inch titanium intake valves.
Chevrolet Performance's LS7 7.0L crate engine package includes a Corvette production-style engine with a dry sump oil pan. You'll need to supply the external oil supply and oil lines to the engine, but the rest of the assembly is fully dressed, including the manifold assembly with injectors and electronically controlled throttle body, and log-style exhaust manifolds.

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 tuning adjustments.
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 exhaust system)
• 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 operated throttle body
• 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
• The programmed controller

SuperMatic 4L75-E Four-Speed Automatic Transmission
Developed by Chevrolet Performance engineers, the 4L75-E Supermatic has been proven, in real-world conditions, to be one of the most robust automatic transmissions on the market. Featuring a torque capacity of 650 lb.-ft, this makes the 4L75-E suitable for many of Chevrolet Performance's most powerful crate engines. The Supermatic 4L75-E is the size of the 4L65-E transmission so it's smaller than the 4L80-E but offers more torque capacity than comparably sized product offerings. The 650 lb.-ft. torque capacity makes it the flexible alternative to the 4L80-E when transmission tunnel clearance is an issue.

Features:

• Features 5-pinion gear sets, heat-treated stator shaft splines, induction-hardened turbine shaft, 8-friction plate 3-4 clutch, and specific valve-body calibration
• Unique, high-strength input housing
• Higher-capacity servo
• More robust 3-4 clutch
• Larger 2-4 band
• Based on the 4L65-E/4L70-E
• Gear ratios: 1st: 3.06, 2nd: 1.62, 3rd: 1.00, 4th: 0.70
