Competition Cams takes care of our custom grind blower series of camshafts. The ECS Bigger Blower camshaft features lift in the .610″ range and high 230’s duration on a 115LSA. We recommend this cam only on larger cubic inch motors, 383+ ci. This cam makes 60+ rwhp / 40+ rwtq on a supercharged car. The cam is not for the faint of heart, higher stall converter is needed in automatic vehicles.
