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! Designed for retrofit installations in older vehicles, for easier and quicker installation and operation without the need for guessing which parts will work with your combination.
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.

Each kit delivers a fully assembled crate engine, transmission and the installation kit to get it all running in your project vehicle - including the flywheel, clutch disc, pressure plate, hydraulic throw-out bearing (lines and master cylinder not included), fasteners and instruction sheets. 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 engineers did all the hard work of designing and calibrating perfectly matched powertrain systems - and they covered them with a 24-month/50,000-mile limited warranty.

ZZ454/440 454ci, 440HP / 500TQ Engine
Chevrolet Performance engineers took the 454 HO - with its super-tough, all-forged reciprocating assembly - and matched it with a set of higher-flow, oval-port aluminum cylinder heads to pick up an additional 15 horses, while still offering 500 ft/lbs of torque. They dubbed it the ZZ454/440, and it's an affordable high-performance Big-Block for any chassis you can stuff it in.

The ZZ454/440 uses the new cylinder block casting for greater strength and performance, while the aluminum heads use smaller, 110cc combustion chambers to boost compression to 9.6:1, up from 8.5:1 on the 454 HO. Then matched the airflow capability with a high-lift, hydraulic roller camshaft that delivers great idle quality and requires no periodic lash adjustments.

This crate engine package includes the ZZ454/440 assembled with a water pump, balancer, aluminum intake manifold, and a 14-inch flexplate. To simply finish up this package, you will need a carburetor, starter, ignition system, and other accessories. Don't sweat it, JEGS has all the components you need to get this big-power Big-Block started.
