LS7 / 7.0L Crate Engine
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.

Supermatic 6L80-E Transmission
Chevrolet Performance 6L80-E SuperMatic Six-Speed Automatic Transmission is based on the production version six-speed transmission found in many modern rear-wheel-drive GM vehicles. This aftermarket version of the transmission is enhanced with upgraded internal components that allow for a much higher torque output of 650 ft.lbs. that is 45 percent higher than regular production models. Equipped with a 4.02:1 first gear for strong off-the-line acceleration and a 0.67:1 final gear for smooth highway cruising, the 6L80-E is perfect for any project vehicle running a Chevrolet LS engine in a RWD configuration.

Engine Control Module and Harness
A precisely calibrated engine control module is essential to making your modern fuel-injected engine perform in your older vehicle. 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 controller 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. The kits also include detailed instructions to help you do it right the first time, even if you have no experience.
INSTALLATION NOTES:

- Comes assembled with 14-inch 168-tooth flywheel

Motor Vehicles
WARNING: Motor vehicles contain fuel, oils and fluids, battery posts, terminals and related accessories which contain lead and lead compounds and other chemicals known to the State of California to cause cancer, birth defects and other reproductive harm. These chemicals are found in vehicles, vehicle parts and accessories, both new and as replacements. When being serviced, these vehicles generate used oil, waste fluids, grease, fumes and particulates, all known to the State of California to cause cancer, birth defects, and reproductive harm.
Tools:
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemically treated lumber. Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To reduce your exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
