CROW CAMS PERFORMANCE CAMSHAFT TO SUIT HOLDEN L67 SUPERCHARGED 3.8L V6

Stage 1

This Crow cam is designed for use on totally stock heads and stock components up to 6000 rpm. It is recommended to upgrade valve springs to increase performance and allow shifting over 6000 where peak power is made. PCM programming required. Expect gains of 26-37kW depending on your car's current configuration.

Stage 2

This Crow cam is designed for supercharged or nitrous applications on ecotec and L67 bottom ends. It produces the highest power and torque figures than any cam grind currently available with stock heads. An even smaller pulley can be used compared to CAM604. Peak power is 200rpm higher than CAM604. Upgraded valvetrain is mandatory (cam packages available through another ad). PCM programming required. Expect gains of 30-45kW depending on your car's current configuration.

Stage 3

This Crow cam is not for the fainthearted! CAM606 was developed to maximize the HP of an L67 in an all out build i.e stroked, balanced, blueprinted, etc. CAM676 requires ported heads with machined valve guides and a complete valvetrain upgrade. Given the base circle diameter varies between lobes custom length pushrods are also required (cam packages available through another ad). PCM programming essential. No other cam makes the power of this cam in a 3.8L, period. Idle is similar to CAM605 with roughly 13 inches of vacuum. Expect gains of 40+kW depending on your car's current configuration.
