For comparable naturally-aspirated alternatives, explore the LS3 engine for Corvette applications with similar displacement and output. Transmission compatibility is critical pair with our 6L80 automatic transmission for optimal performance delivery. Learn about LS platform engineering on Wikipedia’s General Motors LS engine family. All units tested for reliability with complete warranty protection.
L99 fitment is specific to the fifth-generation Camaro SS with automatic transmission (2010–2015). The L99 is not interchangeable with the manual LS3 in the same Camaro without AFM system modifications. Our VIN verification confirms the L99 for your Camaro SS automatic before it ships.
Fifth-generation Camaro SS automatic owners comparing a used engine, a remanufactured engine, and an OEM engine for the L99 benefit from the factory AFM-automatic calibration being preserved. A used GM L99 engine from a verified low-mileage Camaro SS gives you the factory 6.2L AFM V8 as an OEM engine — the original 400 hp output, the factory AFM calibration for automatic Camaro operation, the original LS architecture — at a price no remanufactured engine from a truck 6.2L core delivers at Camaro SS L99 specification. Choosing a used L99 OEM engine restores the factory Camaro SS performance this variant was built to deliver.
Every used GM L99 engine ships with up to a 90-day warranty and arrives within 2 to 5 business days. Installation is not included. These are genuine GM OEM engines, and we stand behind every unit.
