Katech LS3 Track Day Camshaft

Katech LS3 Track Day Camshaft

LS3 Performance Camshaft Engineering with 500 RWHP Potential in an Appropriately Configured Build.

The Katech LS3 Track Day Camshaft is designed for LS3 performance builds targeting 500 rear-wheel horsepower with the proper supporting modifications. Its profile features 228°/242° duration at .050", .627"/.622" valve lift with a 1.70:1 rocker ratio, a 113° lobe separation angle, and +4° camshaft advance.

This is a 3-bolt camshaft. Applications originally equipped with a single-bolt camshaft sprocket, such as the 2010 Camaro LS3, require conversion to a compatible 3-bolt sprocket with the correct camshaft position trigger configuration.

For automatic transmission builds, this camshaft is not recommended for use with an OEM torque converter. Contact Katech Technical Sales to discuss converter selection and supporting components for your specific combination.

Katech's camshaft development draws on decades of racing engine experience and Optron Spin Cell valve motion analysis. Actual horsepower, idle quality, driveability, and operating range depend on the complete engine combination, supporting modifications, and ECU calibration.

Technical Specifications

Supporting Valvetrain

The Katech LS3 Track Day Camshaft should be paired with valvetrain components selected for its profile, valve lift, and intended operating range. Contact Katech Technical Sales for valve spring, lifter, pushrod, retainer, and locator recommendations for your specific build.

Fitment

Chevrolet / General Motors: LS3 Engine Applications with a Compatible 3-Bolt Camshaft Sprocket.

Applications originally equipped with a single-bolt sprocket require a compatible 3-bolt conversion. Confirm the sprocket's camshaft position trigger configuration matches the engine and ECU requirements.

Automatic Transmission Applications: Use with an OEM torque converter is not recommended. Contact Katech Technical Sales to discuss an appropriate converter for your build.

Important Installation Notes

• Camshaft Sprocket: A Compatible 3-Bolt Sprocket Is Required
• Single-Bolt Conversion: Applications Such as the 2010 Camaro LS3 Require a Sprocket Change
• Trigger Compatibility: Confirm the Correct Camshaft Position Trigger Configuration for the Engine and ECU
• Torque Converter: OEM Torque Converters Are Not Recommended for Automatic Transmission Builds
• Camshaft Timing: Verify Installed Timing Against the Cam Card
• Rocker Ratio: Confirm Actual Valve Lift for the Rocker Ratio Used
• Valvetrain Setup: Verify Valve Spring Suitability, Installed Height, Coil Bind Clearance, and Retainer-to-Seal Clearance
• Piston-to-Valve Clearance: Check Clearance for the Completed Engine Combination
• Pushrod Length & Lifter Preload: Verify During Installation
• ECU Calibration: Match the Calibration to the Camshaft and Supporting Engine Components
• Professional Installation: Recommended for Proper Setup and Verification
