More about Connect & Cruise Crate Powertrain Systems

The Complete Performance Package!

When it comes to factory-engineered performance and convenience, nothing beats Chevrolet Performance’s industry-exclusive Connect & Cruise powertain systems. With one package you get the engine and automatic or manual transmission and, we deliver it for less than the cost of buying the components separately.

Our engineers matched the engines and transmissions for optimal performance and durability, so you can wring out every horsepower with total confidence! The specially calibrated controllers for fuel-injected engines are designed for retrofit installations in older vehicles, for easier and quicker installation – and more importantly – operation without the need for third-party tuning.

The Connect & Cruise lineup even includes several emissions-compliant E-ROD systems in both automatic and manual.

We did the work to design and calibrate perfectly matched powertrain systems and covered them with a 24-month / 50,000-mile limited warranty.

Chevrolet Performance pioneered the performance crate engine, so when it comes to performance innovations that save time, money and guesswork, we once again lead the way! All you have to do is install, connect, and start cruising!

NOTE: All components, engine, transmission, controllers and installation kits (where applicable) are ordered and delivered separately.

Additionally, all engines require a front-end accessory drive system. The instructions included with each kit lists recommendations and Chevrolet Performance offers several configurations to suit different applications that also allows the installer to easily delete air conditioning.

Chevrolet Performance recommends the LS1 Engine Installation Guide P/N 88959384, which illustrates basic procedures and offers helpful tips on installing an LS engine into older vehicles.

Carb Loading for BIG Power at the Track or on the Street!

Are you unsure about all of those LS engines that are on the no-carb diet plan? Fear not, we have a tasty LS376 (6.2L) that is just waiting for you to add carburation! Using the LS3 engine as its foundation, the LS3/515 crate engine adds the racing-derived ASA Hot Cam and a carbureted intake system to produce 533 horsepower at a high-revving 6,600 rpm and 477 lb.-ft. of torque at 5,200 rpm. The ASA camshaft is a hydraulic roller with .525-inch lift on both sides, along with 226 degrees of duration on the intake side and 236 degrees on the exhaust side. Coupled with a tight, 110-degree lobe separation angle, it helps the engine deliver excellent throttle response and breathe exceptionally well at high rpm. This engine comes with a wet sump oil pan from the Chevrolet SS performance sedan and a pair of high-flow, rectangular-port LS3 heads, as well as Chevrolet Performance’s unique, “spider” intake manifold for carburetors. GM recommends the Holley 770-cfm carb. (P/N 19170093) and you’ll need the LSX Controller (P/N 19171130) to get the engine running. The 4L70-E four-speed automatic overdrive transmission backs the LS376 / 515 with strength and durability. It is based on the venerablel60E family of transmissions, but features five-pinion gearsets, heat-treated stator shaft splines, induction-hardened turbine shaft, seven-plate clutch and specific valve-body calibration for increased power handling capabilities.

Put this combo to work in your classic cruiser and enjoy. It’s a great engine and trans. combo for your resto-mod classic or 1970s-era muscle car or hot rod pickup!
