Camshaft

The Speed Inc TSP-LS3Stg1-3B camshaft is engineered for LS3, LSA, and L92 supercharged engines, offering a balance of performance and drivability. With a 223/231 duration and .629"/.629" lift on a 115 LSA, it provides a mild idle lope and great stock-like driving manners once properly tuned. This camshaft is designed to work with factory torque converters and is compatible with M6 or automatic transmissions. It is recommended for LS3, LSA, or LS2 engines utilizing L92/LS3 rectangular port cylinder heads, requiring a compression ratio of 10.0:1 or higher. Installation of this camshaft requires TSP/PAC Dual .660 Valve Springs, and it operates within an RPM range of 1800-6500. Notably, an aftermarket stall converter or upgraded rear gears are not required, making it a straightforward upgrade for factory setups. Estimated power increases range from 45-50+ horsepower. This camshaft is exclusively offered in a 3-bolt design. If your vehicle is equipped with a single-bolt factory camshaft, you will need to purchase a three-bolt conversion kit. This kit includes the correct 4x upper timing gear for the camshaft position signal and an ARP camshaft bolt kit. Conversion kits with an upgraded timing set are also available for those looking to replace the entire set.
