An affordable LS crate engine with power and durability

If you’re looking for an affordable alternative to a used LS engine for your swap project, check out Chevrolet Performance’s new LC9 5.3L engine. 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.

Available in two configurations: a conventional 5.3L assembly, or the E-ROD version that also includes performance-enhancing camshaft phasing.

The LC9 5.3L engine package includes an aluminum engine block, intake manifold, throttle body, and fuel rail. It’s a great choice for hot rod cruisers and off-roader projects, where torque and dependability are the priority in maximum horsepower.
