F-35 Stage 4 LS3 N/A Camshaft

The Texas Speed & Performance (TSP) Stage 4 "F-35" LS3 N/A Camshaft is engineered to deliver maximum power 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 (109.5 ICL), this camshaft is designed for aggressive performance and offers adequate piston-to-valve clearance on stock short blocks. This camshaft is specifically designed for engines with 6.0L or 6.2L displacements equipped with rectangular port heads, targeting a compression ratio of 10.5:1 or higher. The power gains are substantial, estimated at 93 horsepower and 27 ft-lbs of torque over the factory LS3 camshaft, with peak horsepower achieved at 6600 RPM. It operates effectively within a 2000-7000 RPM range. For optimal performance and streetability, a minimum aftermarket stall converter of 3600 RPM is required for automatic transmissions, with a 4000+ RPM stall recommended for track use. An upgraded rear gear of at least 3.42 is also considered optimal. For proper operation, TSP recommends their .660 Dual Valve Spring kit. Note that this camshaft is exclusively offered in a 3-bolt design. If your vehicle uses a single-bolt factory camshaft, a three-bolt conversion kit is necessary, which includes a 4x upper timing gear for the camshaft position signal and an ARP camshaft bolt kit. The F-35 camshaft is not recommended for daily drivers but can be tuned for such use, positioning it as a "weekend warrior" camshaft for street/strip applications.
