Crow Cams 'Tough Idle' Cam Range
Hot Rod and Street Machine builders often ask for cam combinations that will produce a tough idle and engine note without sacrificing street driveability or engine reliability. The range of Crow tough hydraulic grinds
are designed with increased overlap to produce a lumpy idle that will stand out in the crowd.
Options are available for standard or hi stall converters with good power and strong torque through the RPM range.
Please note tough cams will have low vacuum due to the tight lobe centre.
