The Magic Stick line of camshafts is the most popular line of camshafts Texas Speed offers. The Magic Stick 3 camshaft is designed to be a all out max effort nitrous camshaft to get maximum power from stock displacement engines. The Magic Stick camshafts require a high quality double spring kit such as the PAC .660" double spring kits. With the MS3 camshaft, the automatic-equipped customer must have at least a 3800+ stall speed converter. Tuning will also be required in both automatic and manual applications.
