The BTR LS3 Stage 1 V2 is the entry point into the LS3 Stage lineup for GM LS-series engines. Developed in-house and refined for more power and torque throughout the curve than BTR's earlier LS3 cams, its lobes were Spintron and engine-dyno tested to hold BTR's valvetrain stability and durability standards. E85 fuel is recommended in higher-compression applications.
