How to use this Quick Identification Guide
1. Measure camshaft length. Measure from under the cam head to the beginning of the lock ring groove.
2. Locate camshaft length in the Camshaft Quick Identification Guide. Camshafts are listed in order of length, from shortest to
longest.
3. After finding camshafts in the Cam Length column, determine camshaft head style, using the Head Styles chart and head width
dimensions.
4. Narrow your final selection by Diameter at Spline End and Number of Splines, Diameter at Spider and any other information listed.
