Part #2139 Cadillac V8 Magnum Roller Timing Set

Thank you for choosing COMP Cams® products; we are proud to be your manufacturer of choice.

Please read this instruction sheet carefully before beginning installation, and also take a moment to

review the included limited warranty information.

The 3 keyway crank sprocket allows adjustment of the crankshaft timing by ±4°. By changing the cam

timing, enhancements to the camshaft characteristics can be achieved. For example, retarding the cam

timing will increase high rpm horsepower, and advancing the cam timing will increase low end torque.

The following examples illustrate which timing mark is used with its corresponding keyway.

To retard the camshaft timing, use the Y timing mark on the crank sprocket and the retard keyway

shown below.
