LT4 376ci / 6.2L, 650HP / 650TQ EngineThe all-new LT4 supercharged 6.2L V8 is the latest high-tech small-block crate engine from Chevrolet Performance. The perfect balance of performance and efficiency, the LT4 leverages the technologies introduced on the 2014 Corvette Stingray's LT1 Gen-V small block, including Direct Injection and continuously Variable Valve Timing. The LT4 is based on the same architecture as the LT1 engine, with several unique features designed to support its higher output and the greater cylinder pressures created by forced induction. It includes the Rotocast A356T6 aluminum cylinder heads that are stronger and handle heat better than conventional castings, lightweight titanium intake valves and stronger forged aluminum pistons. While advancing the supercharging technologies established with the previous-generation Corvette ZR1's LS9 engine. This engine features the more-efficient, more-compact 1.7L Eaton R1740 TVS supercharger, which spins at up to 20,000 rpm.

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.

From small-block V8 engines to high-performance LS and LT engines, there's a powertrain option for every enthusiast. The package also includes a variety of transmission options, including automatic and manual transmissions. SuperMatic 4L75-E Four-Speed Automatic TransmissionDeveloped 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.

With a long stroke crank, full counterweights have an advantage because they’re easier to balance (for one thing, they require less heavy metal). Another advantage is that the actual counterweights can become smaller when there are eight of them. LT4 connect and cruise options range in price from around $26,000 to just over $27,000, depending on options.

The Origin will help expand mobility options for seniors, people who are blind or have low vision, and other communities that have traditionally faced barriers in access to reliable transportation. GM is manufacturing the Origin in Michigan at Factory ZERO, supporting and creating American jobs, promoting economic growth, and advancing the long-term success of the U.S. manufacturing sector and America’s automotive industry. As the standard engine in the fifth-generation Camaro SS and C6 Corvette, the high-revving, deep-breathing LS3 6.2L is poised to go down in history as one of Chevrolet’s best and most versatile engines.

Whether you're a seasoned mechanic or a first-time builder, GM Connect and Cruise makes it easy to achieve the performance and reliability you desire. 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, "plug-and-play" installation that is quick, easy and intuitive. It's backed by the 4L65-E four-speed overdrive automatic, which enables great highway cruising performance and fuel economy with the durability of hardened internal parts and five-pinion gearsets. With Chevrolet's Connect and Cruise Crate Powertrain System, all the hard work, designing and calibrating the ECM has already been done for optimal compatibility and performance.

During this mock-up phase, figure out where you’re going to mount the fuse box, ECM, and TCM. So, if you're in the market for a new powertrain system, be sure to consider GM Connect and Cruise. With its wide range of options, warranty coverage, and potential rebate offer, it's a package that delivers both power and peace of mind.

As I type this, I just did a 500-mile second oil change and have a few things to sort. In the meantime, I thought it’d be fun to walk everyone through everything you need to wire to get a Chevrolet Performance Connect & Cruise system started for the very first time. If you are planning to use GM Connect and Cruise packages in a vehicle that will be driven on public streets or highways, it is important to ensure that the vehicle complies with all applicable emissions laws and regulations.

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.

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.

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.

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.

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.

GM Connect and Cruise packages can be purchased from participating U.S. dealers or Chevrolet Performance Authorized Resellers. These authorized dealers and resellers have the knowledge and expertise to help you select the right powertrain package for your vehicle and answer any questions you may have.

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 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!

The rebate form and details can be found at chevrolet.com/performance/offers. It is important to carefully read and follow the instructions on the rebate form to ensure that your rebate is processed correctly. LT4 / SuperMatic 8L90-E Installation KitGet your new 8-speed automatic bolted to your new engine with this SuperMatic 8L90-E installation kit. Kit includes all the correct components that Chevrolet Performance offers to easily mate your new engine and trans.

In the 385-horsepower SP350/385, Fast Burn cylinder heads and LS-style beehive valve springs combine for incredible power. With either the T56 Super Magnum 6-speed manual or 4L65-E 4-speed automatic on board, you can expect both world-class performance and Connect & Cruise convenience. For Switched or Key On, Power, the harness includes a wire marked Ignition. This branch of the harness features other connections for the accelerator pedal, the MIL wire (for a Check Engine light), and your OBII port, so you’ll most likely run this Ignition wire into the cabin with those. You’ll need to find a wire that becomes hot when the key is on (or in the start position). To begin, first lay out and route your engine and transmission harnesses (it may be best to do this prior to installation if you don’t have room behind your engine and/or above your transmission).

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.

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.

The dealer or reseller will provide you with all the necessary information and assist you with the ordering process. They will also be able to provide you with an estimated delivery time for your package. It is important to read and understand the terms and conditions of the warranty before purchasing a GM Connect and Cruise package. This will help you understand what is covered under the warranty and what is not. If you have any questions or concerns about the warranty, it is recommended to contact your local GM Dealer or Chevrolet Performance Authorized Reseller for more information. Every Cruise Origin will help reduce the world’s reliance on oil, as well as the emissions that disproportionately burden historically underserved communities.

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.
