Product Description
Texas Speed TSP 224/228 Camshaft for LS Engines
224/228 .600"/.600" 112 LSA | 3-Bolt Pattern | Fits 1997-2013 LS-Based GM Engines
The Texas Speed TSP 224/228 camshaft is a popular LS camshaft choice for builders who want the proven 224 intake lobe paired with additional exhaust duration. Its 112 LSA is designed to bring the powerband in sooner while delivering an aggressive idle character and strong street drivability. This 3-bolt camshaft is well suited for naturally aspirated and boosted LS combinations looking for a capable street-performance cam upgrade with balanced intake and exhaust timing.
Key Features & Benefits
- 224/228 Camshaft Profile: Features 224 degrees of intake duration and 228 degrees of exhaust duration, providing additional exhaust-side timing for LS combinations that benefit from a slightly larger exhaust lobe.
- .600"/.600" Valve Lift: Delivers .600" lift on both the intake and exhaust sides, making proper valve spring selection, retainer-to-seal clearance, and piston-to-valve clearance verification essential.
- 112 Lobe Separation Angle: The 112 LSA is designed to bring the camshaft's power in sooner while delivering a more aggressive idle sound than wider LSA street camshaft profiles.
- Street-Friendly Performance Profile: A strong option for compatible LS street, strip, naturally aspirated, supercharged, and turbocharged combinations seeking improved airflow potential with usable drivability.
- 3-Bolt Camshaft Pattern: Designed for LS engines using a 3-bolt camshaft configuration. Engines originally equipped with a 1-bolt camshaft require the appropriate 3-bolt conversion components.
