Brian Tooley Racing GM LS Truck Stage 4 Version 1 Camshaft
The Stage 4 is designed for the truck owners with peak power in mind, a 3000-3200 RPM torque converter will be needed to ensure good idle and drivability characteristics. BTR truck cams were designed with low lift so GM LS2/3/6 valve springs and OEM pushrods can be used, making these the most affordable cams available. When installed in an otherwise stock 5.7 LS1, this camshaft was good for over 370 whp. As an alternative, check out BTR's V2 truck cam series. Requires a three bolt cam gear.
