LS Classic Series ’57 Fuelie Crate Engines GMLS9014

Styled after a vintage fuel-injected big block, the LS Classic '57 Fuelie (GMLS9014) is a new long block displacing 376 cubic inches (6.2L), with a 10.7:1 compression ratio on an internally balanced aluminum block and heads underneath the retro looks.

What's assembled on it

Fuel injection hardware, the throttle body, and the intake manifold are already mounted, and a computer with its matching wiring harness handles the EFI side, paired with a flexplate for automatic-transmission use. The valve covers, harmonic balancer, timing cover, and oil pan round out the top end. There is no water pump, air cleaner, flywheel, distributor, or supercharger included, and the camshaft is a hydraulic roller riding on a one-piece rear main seal.

Where this engine fits

Builders use this engine for classic muscle car restorations, hot rods, and LS swap projects that want the drivability of modern fuel injection without losing a vintage look under the hood. Because the exhaust system, cooling components, and transmission are not part of the package, plan on sourcing those separately, and check that your vehicle's drivetrain and cooling setup can support an LS swap before ordering.

Common questions

Does it include an ECU? Yes, the fuel injection system comes with its own computer and matching wiring harness, pre-calibrated at the factory.

What's the horsepower rating? LS Classic doesn't publish one for this engine; output depends on your fuel and tuning setup.

Does it come with a water pump? No, that and the rest of the cooling system are sourced separately for this build.
