It is designed for 383 cubic inch and larger naturally aspirated LS engines with cathedral-port cylinder heads, with 238\/253 duration, .644\"\/.632\" lift and a 111 degree lobe separation matched to stroker displacement and airflow.\u003c\/p\u003e\u003cp\u003eThe Stage 2 produces a very aggressive performance idle with aggressive midrange and strong upper-rpm power for serious street and street\/strip builds. Texas Speed develops the lobes in-house and verifies valvetrain control with Spintron testing. Aftermarket cathedral-port heads and an upgraded intake are strongly recommended, upgraded valve springs and supporting valvetrain parts are required, and custom tuning is required. Because it is more aggressive than Stage 1, it should be paired with a performance-focused drivetrain, converter and gearing.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eDuration at .050\": 238\/253\u003c\/li\u003e\n\u003cli\u003eValve lift: .644\"\/.632\"\u003c\/li\u003e\n\u003cli\u003eLobe separation angle: 111 degrees\u003c\/li\u003e\n\u003cli\u003eIntake centerline: 109 degrees\u003c\/li\u003e\n\u003cli\u003eMinimum recommended displacement: 383 cubic inches\u003c\/li\u003e\n\u003cli\u003eCylinder head type: Cathedral-port LS\u003c\/li\u003e\n\u003cli\u003eRecommended combination: Aftermarket cathedral-port heads and intake manifold\u003c\/li\u003e\n\u003cli\u003eBest use: Naturally aspirated street\/strip and performance stroker builds\u003c\/li\u003e\n\u003cli\u003eIdle quality: Very aggressive performance idle\u003c\/li\u003e\n\u003cli\u003ePowerband: Aggressive midrange with strong upper-rpm\u003c\/li\u003e\n\u003cli\u003eValve springs: Upgraded valve springs and supporting valvetrain required\u003c\/li\u003e\n\u003cli\u003eTuning: Custom tuning required\u003c\/li\u003e\n\u003cli\u003eVehicle usage: Street performance, mid range\u003c\/li\u003e\n\u003cli\u003eChop level: Choppy\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e This camshaft is designed for 383 cubic inch and larger LS stroker combinations and is not intended as a general replacement cam for stock-displacement engines.
