You sacrifice some low-end torque in pursuit of more power further up the rpm range, but get an idle that is DISTINCTIVELY BTR! With more mid-range torque than the previous Stage 3 grind, this is still a towing-friendly cam, just not ideal for the daily hauler. An aftermarket converter is recommended with this grind. V2 CAMSHAFTS: Specific Benefits?? Modified cam centerlines for increased mid-range torque Each ??stage?? is born from its own specific cam core. NO SHARED CORE CORES ARE USED. With a specific core per cam, maximum heat treatment penetration is achieved.
