The L99 to LS3 conversion kit includes most items you will need to convert your L99 Engine to an LS3. By converting your L99 to an LS3 you are able to install an aftermarket camshaft providing you better performance and power from your Camaro. Once the DOD/AFM is disabled with a tune your tuner can properly tune your Camaro to optimize the power out of your newly installed cam.


All the items used in our kit are Genuine GM parts. With everything we have tested the factory parts work the best when it comes to preventing leaks from happening after your cam has been installed.



Note: The L99 engine is ONLY available in Camaro's with the Automatic transmission.



Note: Tuning is required for proper operation.



Note: Cam NOT supplied in kit. Torque converter maybe required with certain cams.
