Additional Components Required:

To complete the installation of this package, you will need additional components such as the Heads & Camshaft Bolt Gasket Kit, available here.

This package uses a 3-bolt camshaft. If your engine currently uses a single-bolt cam, you may need to purchase the 3-Bolt Conversion Kit, available here.

AFM and VVT Considerations:

If your vehicle is equipped with Active Fuel Management (AFM) and/or Variable Valve Timing (VVT), you will also need:

• DoD/AFM Delete Kit, available here.
• VVT Delete Kit, available here.

Vehicle Recommendations:

• Automatic Transmission: A 3000+ stall torque converter is required for automatic vehicles.
• Manual Transmission: This package works well with stock rear-end gears, but performance can be enhanced with 3.73 or 4.10 gears.

Aggressive Sound:

This camshaft provides a loping idle and a noticeable chop, giving your LS3 engine a race-ready sound while maintaining excellent drivability.
