LC9 5.3L Crate Engine

320 hp @ 5,400 rpm / 335 lb.-ft. @ 4,000 rpm


Affordable LS Power

Our LC9 5.3L crate engine makes a great, affordable alternative to a used LS engine for your project. It is based on the workhorse power plant used in hundreds of thousands of GM trucks, including the Chevrolet Silverado and Suburban. It’s rated at 320 horsepower and tuned to deliver exceptional torque at low rpm.

The LC9 features a lightweight aluminum block and comes with the intake manifold, throttle body and fuel rail. It’s a great choice for hot rod cruisers and off-roader projects, where torque and dependability is the priority over maximum horsepower.

We also offer the LC9 in E-ROD emissions-compliant kits for 2WD and 4WD applications, as well as Connect & Cruise crate powertrain systems for 2WD and 4WD applications. Connect & Cruise systems include a four-speed automatic transmission and all necessary controllers and wire harnesses.
