After countless designs, Spintron sessions, and Superflow engine dyno tests, the team delivers a profile designed to move your GM Gen 3\/4 LS truck or SUV with confidence. The goal was a cam that broadens usable power while preserving street manners, idle quality, and compatibility with common drivetrains. The resulting profile aims to provide a strong, broad torque curve and a satisfying throttle response without sacrificing driveability.\u003c\/p\u003e\n\u003cp\u003eThe Truck Norris is built for 1999–2013 GM Gen 3\/4 LS Truck engines, including 4.8, 5.3, 6.0, and 6.2 liter variants. The cam's specifications are 212\/22X duration, lift of .552 inches on both ramps, and a 107 degree LSA behind a 3-bolt pattern, designed to fit standard kit configurations. The combination targets a broader power band and improved torque delivery across the RPM range, with a deeper, more purposeful idle that remains suitable for a street setup when paired with a stock torque converter in many configurations.\u003c\/p\u003e\n\u003cp\u003eKey considerations and notes\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eVVT engines will require a VVT delete kit to operate with this cam profile.\u003c\/li\u003e\n  \u003cli\u003eIf your engine originally used a 1-bolt cam, a 3-bolt conversion kit will be needed for proper fitment.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhy this Cam Stands Out\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eHundreds of hours of in-house cam lobe design and dyno testing informed this profile, targeting broader power and stronger torque in real-world driving.\u003c\/li\u003e\n  \u003cli\u003eThe idle retains a confident, purposeful feel that blends well with many street setups, while still delivering an assertive throttle response when you roll into it.\u003c\/li\u003e\n  \u003cli\u003eThe cam is paired with a robust valve-train kit, including springs, seals, and pushrods, designed to work together in Gen 3\/4 LS trucks.\u003c\/li\u003e\n  \u003cli\u003eDyno-verified development helps translate into practical, usable performance gains across daily driving, spirited passes, and highway merging scenarios.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat You Get and How to Use It\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eCamshaft designed for 1999–2013 GM Gen 3\/4 LS Truck engines (4.8, 5.3, 6.0, 6.2).\u003c\/li\u003e\n  \u003cli\u003eIncludes springs, seals, and pushrods to support installation and durability.\u003c\/li\u003e\n  \u003cli\u003eClear compatibility notes: VVT delete recommended for VVT engines; 1-bolt to 3-bolt conversion as needed.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eIn practical terms, Truck Norris aims to deliver a more responsive feel throughout the power band, improved throttle response, and a satisfying engine character. As with any performance upgrade, results depend on the complete setup, including intake, exhaust, and tuning. Consider this a possible pathway to enhanced driving enjoyment rather than a guaranteed outcome. If you’re upgrading your Gen 3\/4 LS truck, Truck Norris provides a proven, well-documented option to explore, with a balance of power, sound, and drivability that many enthusiasts appreciate during daily driving and weekend sessions alike.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What engines does the BTR Truck Norris Camshaft Kit fit?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Fits 1999–2013 GM Gen III\/IV LS truck engines: 4.8, 5.3, 6.0, 6.2; may need a 3-bolt conversion for 1-bolt cams.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Are there any VVT or installation considerations?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: VVT engines require a VVT delete kit; check if your engine needs a 3-bolt conversion before install.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"BTR Brian Tooley Racing","offers":[{"title":"Default Title","offer_id":42395586920533,"sku":"B0BJ7C1YK7","price":674.45,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0632\/3270\/4597\/files\/btr-truck-norris-camshaft-kit.jpg?v=1775941626","url":"https:\/\/plentytorque.co.uk\/products\/btr-truck-norris-camshaft-kit-for-gen-3-4-ls-trucks-springs-seals-pushrods-4-8-6-2l","provider":"PlentyTorque","version":"1.0","type":"link"}
