The Michigan Motorsports Lumberjack High Lift LS Camshaft Kit is engineered for LS enthusiasts who demand maximum performance and a sound that turns heads. With a reputation for strong top-end power and a deep, lopey idle, this cam delivers exactly what serious street and strip builders look for. Perfect for everything from daily-driven trucks to weekend performance cars and LS swaps, the Lumberjack cam is designed to take full advantage of your engine's airflow potential—especially when supported by headers, tuned ECUs, and upgraded converters. Choose the valve spring setup that best fits your goals: Beehive springs offer excellent valve control in naturally aspirated, moderate-RPM builds. Dual valve springs are the preferred option for aggressive cam profiles, high RPM builds, or boosted/nitrous applications. Whether you're looking to wake up your 5.3L truck or push a 6.0L swap past the 500HP mark, the Lumberjack camshaft is built for durability, drivability, and dyno-proven results.
