Chevy Corvette LS1 Base 5.7L V8 Engine Transmission Loom & ECU

This is a complete used LS1 swap package pulled from a C5 Corvette: a 5.7-liter aluminum-block V8 factory-rated at roughly 345 horsepower, its matching transmission, the original Corvette ECU tuned for LS1 specs, and the full engine wiring loom, sold together rather than as separate parts.

What is included with the engine

Alongside the block itself, also bundled are the pictured throttle body, fuel rails, intake manifold, sensors, and remaining accessories shown with the listing, plus either a 4L60E automatic or a T56 6-speed manual transmission as the gearbox paired to this engine. Confirm with us which transmission accompanies the specific unit you are buying.

Condition and what to expect

As a used pullout, this engine has been removed from a donor vehicle rather than built new; the listing describes it as compression-tested and inspected, with low mileage, and shipped from the USA in a secure crate. Warranty coverage is available on request, so ask about current terms before you commit to a build around it.

Q: Will this bolt into a non-Corvette chassis? The listing names LS swap destinations including Chevrolet C10, Chevelle, Nova, and Camaro, Pontiac GTO and Firebird, Nissan 240SX and RX-7, BMW E36/E46, and Jeep Wrangler, among classic trucks, but always confirm your specific mounts and wiring against this engine's loom and ECU first.

Q: Does the OEM ECU need a separate tune? It is described as already tuned for LS1 specifications, though confirming compatibility with your intended wiring setup is still worth doing before installation.
