Overview

Chevrolet Performance Connect and Cruise 376/480 HP LS3 Crate Engine with 6L80E Transmission Combos

The Chevrolet Performance Connect and Cruise 376/480 HP LS3 Crate Engine with 6L80E Transmission Combo is an all-in-one, factory-matched powertrain kit designed by General Motors for custom car builders and classic hot rod restorations. This specific plug-and-play system combines a high performance 6.2L LS3 V8 engine equipped with a racing-inspired camshaft, a modern 6-speed automatic transmission, and all the standalone electronics needed to make them function together seamlessly in a vintage vehicle without third-party tuning. Eliminate the guesswork of mismatched parts!

What's included:

* The Crate Engine: A fully assembled LS376/480 engine package complete with intake manifold, throttle body, fuel rails, ignition coils, and water pump
* The Transmission: A robust 6L80-E 6-speed automatic transmission with an included torque converter
* Electronics and Wiring: Standalone engine (ECM) and transmission control modules, a specialized drive-by-wire throttle pedal, oxygen sensors, and a mass airflow (MAF) sensor
* Installation Hardware: An installation kit providing the necessary bolts and cross-component hardware to marry the engine and transmission together

Key benefits of this combo:

* The "Hot Cam" Advantage: By upgrading the factory base LS3 cam to the GM Hot Cam, this engine gains a rougher, muscle-car idle and pushes horsepower from the standard 430 hp up to 480+ hp
* True Standalone Operation: The included computers are specially calibrated for retrofit vehicles. They do not require integration into modern anti-theft systems or production vehicle sub-modules. All it needs to run is power, ground, an electric cooling fan, and a high-pressure fuel pump
* Modern Driving Dynamics: Pairing the engine with a 6-speed 6L80-E gives classic vehicles the aggressive launch of a low first gear alongside quiet, fuel-efficient highway cruising
