Olds Camshafts

Usage Notes:

How cams are organized:
The cam files listed below are ranked in the order of increasing Intake Duration. Cams with the least duration are listed at the top of the chart and are the more mild, street cams (see note on 0.050-timing, below). As you move down the chart, the intake duration increases, an indicator of more high-performance profiles.
Note: Most cam file timing values listed below use seat-to-seat timing specifications (these cams are most accurately modeled in the Dyno2000), however, some cams may have 0.050-lift-timing-method specs. Since the duration measured at 0.050-lift is lower than that at seat-to-seat timing, these cams will appear near the top of the table even though they may not be mild, street cams (refer to the Description column for more information on camshaft application).
