Stage 4 "F-35" LS3 N/A Camshaft

The Texas Speed & Performance TSP Stage 4 "F-35" LS3 N/A Camshaft is a high-performance upgrade for LS2, L76, and LS3 engines featuring L92/LS3 rectangle port cylinder heads. With specifications of 235/248 duration, .649/.615 lift, and a 111 LSA, this camshaft is designed to deliver significant power gains. Engineered for all-out performance, this camshaft provides an estimated 93 flywheel horsepower and 27 ft-lbs of torque increase compared to a stock LS3 camshaft. Power gains are noticeable from 3,100 RPM, with strong pulling power from 4,500 RPM up to the 6,600 RPM peak horsepower. It is best suited for engines with a desired compression ratio of 10.5:1 or higher and operates effectively within a 2000-7000 RPM range. For optimal performance and streetability with automatic transmissions, a minimum 3,600 RPM stall speed torque converter is recommended, with a 4,000+ RPM stall speed benefiting track use. An upgraded rear gear, with a minimum of 3.42, is also optimal. This camshaft requires the TSP/PAC .660 Dual Valve Spring set. It is important to note that this camshaft is only offered in a 3-bolt design; vehicles with a single-bolt factory camshaft will require a three-bolt conversion kit, including a 4x upper timing gear and an ARP camshaft bolt kit. A complete upgraded timing set conversion kit is also available.
