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. 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. The kits also include detailed instructions to help you do it right the first time, even if you have no experience. Experience the thrill of a powerful, modern engine in your classic car with our comprehensive selection of connect and cruise crate powertrain systems.

These systems work together through “sensor fusion” to create a sensory field around the vehicle that assists in keeping it centered in the lane while elevating the driver’s comfort and convenience. But those instructions are vital (like making sure you prime your engine with oil). The bottom line here is, a billet crank can cost upwards of several thousand dollars – even higher, depending upon the application and the options the purchaser selects. If you have any additional questions or need more information about GM Connect and Cruise, it is recommended to contact your local GM Dealer or Chevrolet Performance Authorized Reseller. They will be able to provide you with the information and assistance you need to make an informed decision about your powertrain needs. After you have submitted your rebate, it may take some time for it to be processed.
Includes Intake Manifold*

Transmission Model
Available with the Hydra-Matic 4L65-E 4-speed automatic transmission, this convenient Connect & Cruise system combines 60 years of Small-Block heritage and surprising ease of installation. There’s no need for a rebuild or recondition when a brand-new 323-horsepower HT383 is available in a convenient Connect & Cruise package. Mated to the SuperMatic 4L70-E 4-speed automatic, this is the easy way to bring serious torque to your classic truck project.
In effort to slice through the windage you’ll sometimes find high performance crankshafts with specially profiled counterweights. They’re often rounded or heavily profiled with a “knife edge” on the leading edge of the counterweight. There’s not a lot of consensus – however, several well-respected engine builders interviewed tend to lean toward the rounded counterweight profile instead of a sharp knife-edge layout. The 461-horsepower 502 HO crate engine packs 558 lb-ft of torque for versatile performance.
Chevrolet Performance LS3/430 HP Connect and Cruise, 6L80E Trans
The result is a surprisingly efficient engine capable of producing 650 horsepower and 650 lb-ft of torque. This LT4 crate engine is offered with a wet-sump or dry-sump oiling system. A controller specially designed for retro-fit application is available. There are also all-new transmission installation kits specially designed to match the LT4 and its 8-bolt crankshaft flange with Chevrolet Performances 4L-series four-speed automatic transmissions and the T-56 Super Magnum six-speed manual. 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!
And please, please, please read and re-read your Chevy Performance instructions. In addition to the included catalytic converters and 50-state legal engine tune, the E-ROD kits include an EVAP system, which collects gas tank fumes, runs them through a charcoal canister, and back into the engine via a purge solenoid. Chevy Performance Connect & Cruise Systems include a Mass Air Sensor and an air filter, but not the air intake itself, which needs to be 4-inches in diameter. I initially ordered a SIKKY intake designed for the LS3, but it lacked an extra port for the PCV systems’ Fresh Air Tube.
GM Connect and Cruise: Powertrain Systems, Store, and eCrate Kits
When you’re dealing with the main and connecting rod journals of the crank, each must be precise in size and shape to create the proper clearance with the respective bearings. It should be no secret that bearings and crankshaft journals never really touch. The crank operates on a fine layer of oil between the respective surfaces. Trouble can begin when the engine is first started, if it is placed under extreme load or if it experiences even a temporary lack of oil supply. It’s at that point when crankshafts can experience bearing to journal contact. That spells big trouble and usually means you have to regrind the crank.
It is also where the crankshaft sees the most stress and it’s also the place where most crankshaft failures take place. With the harnesses in place and various modules mounted, connect as many of the plugs as you can, but leave the ECM and TCM disconnected until priming the engine with oil. This may seem daunting at first, like wrangling a plastic octopus, so just take your time. Also, because the harnesses are universal, you’ll most likely end up with a few long strands that need to be looped and tucked away. For this reason, some of you may prefer a custom harness (or you could shorten the included harnesses). After a few delays (some my fault, some not), I decided to finish the build so I could release content more consistently.
E-ROD kits include catted downpipes, so, once the pipes are in place (fitment can be a challenge — I suggest teaming with an exhaust shop) it’s pretty easy to install the sensors and connect them to the harness. Just like the crank grinding operation mentioned earlier, the polishing job mandates a good amount of skill. Case-in-point is the fact that it’s easy enough to polish a crank right into a slight taper. This can happen when the crank is polished using a back and forth motion. In this case, the polishing job will actually wear the middle of the journal more than the outer edges.
What this means is that the interval between the throws is brought into specification. In a typical V8 fitted with a conventional crankshaft, the rod throws should be exactly 90 degrees apart. For the most part, custom aftermarket cranks are correctly indexed, and the vast majority are “standard” in size (this means they are not ground Under Size). The problem with having six counterweights is that there are actually eight cylinders in a typical V8 (!).
The delivery of the rebate in the form of a debit card may take 6 to 8 weeks. It is important to be patient and allow sufficient time for the rebate to be processed and delivered. Once you have selected the GM Connect and Cruise package that is right for you, the next step is to place your order.
Then conveniently harness that power with the production-based 8L90-E 8-speed automatic perfectly matched to it. Developed with upgraded internal components, Chevrolet Performance’s SuperMatic 6L80-E 6-speed automatic transmission offers an exceptional torque rating of 650 lb.-ft. – a 45 percent increase over regular production versions of the 6-speed automatic. It is also important to note that vehicles equipped with Chevrolet Performance parts that are emissions-related may not comply with U.S., Canadian, and state and provincial laws and regulations regarding motor-vehicle emissions.

Mated to the SuperMatic 4L85-E 4-speed automatic, this Connect & Cruise package is built for convenience and exhilaration. Continuing the legacy of the first Chevrolet Small-Block V8, the ZZ6 Base offers 404 horsepower and a 430 lb-ft torque rating. With the Hydra-Matic 4L65-E 4-speed automatic included, this Connect & Cruise package takes the guesswork out of bringing a performance legacy to your passion project.
Restoration shops and individual owners alike can trust our GM connect and cruise options for superior quality and reliability. Custom-tailored to complement your car's unique needs, these systems ensure a smooth, enjoyable ride that's truly one-of-a-kind. Chevy Performance Connect & Cruise harnesses need two types of positive 12V power to operate and complete a successful startup procedure — Constant & Switched (aka, power that is only on when the key is in the ON position). A generous “fillet radius” will be found in a quality high performance or race crankshaft. The fillet radius is the area between the journal and the cheek of the crankshaft.
