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, automatic or manual transmission, electronic controllers and al the necessary wire harnesses. Even better, 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 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, torque converter and controllers are ordered and delivered separately.

A Big-Inch Alternative to Rebuilding

Don’t bother repowering your trusty Big-Block-powered truck or project vehicle with a rebuild or reconditioned used engine. Our HT502 crate engine is an affordable alternative with more power than our factory installed Big-Block, producing a whopping 541 lb.-ft. of trailer-tugging torque.

It is uniquely suited to pre-1978 trucks, but is adaptable to a variety of applications, and it’s built with our latest-generation block casting with four-bolt main caps. An all-forged rotating assembly delivers exceptional strength and durability, while a mild 8.75:1 compression ratio is suitable for regular pump gasoline at all altitudes and engine loads.

Our assembly comes with the heads and a balancer installed. An induction system, ignition, starter, water pump and other accessories are required to finish the engine. All necessary components are available from Chevrolet Performance.
