Description

The Texas Speed & Performance TSP LS3 Stage 2 Supercharged Camshaft is engineered for LS3, LSA, and L92 applications, aiming to maximize power from 2400rpm and beyond. This camshaft is a prime choice for supercharged LS3/LSA engines, offering a balance for performance enthusiasts looking for a versatile upgrade. Featuring detailed specifications of 227/235 duration, .641"/.649" lift, and a 114 LSA, this camshaft is specifically recommended for LS3, LSA, or LS2 engines equipped with L92/LS3 rectangle port cylinder heads. Even without a supercharger, users can expect typical gains of around 60 rear wheel horsepower on stock LS3 configurations, making it a strategic option for those planning a future supercharger addition. This camshaft is suitable for LS3/LSA M6 cars or automatic transmissions with a 2500rpm or higher stall converter, and requires a VVT/AFM delete kit if applicable. The product details note that factory LS3 camshafts use a single-bolt design. Users can opt for a direct single-bolt replacement or convert to a three-bolt camshaft design common in 1997-2006 LS-based vehicles. A three-bolt conversion kit includes the necessary 4x upper timing gear and ARP camshaft bolt kit, with an option for a complete, upgraded timing set.
