SBC Billet Adj. Timing Set

The COMP Cams SBC Billet Adjustable Timing Set (model 8100CPG) is a precision-engineered double roller timing chain kit designed for small-block Chevrolet V6 engines requiring independent timing control. This billet steel construction delivers the durability needed for high-performance builds while the adjustable design allows tuners to dial in cam timing for optimized power delivery across the RPM range.

The double roller chain design reduces friction and wear compared to single roller systems, extending component life under sustained load. Billet steel construction provides superior tensile strength and fatigue resistance, critical for engines operating at elevated RPM or boost levels. The adjustable keyway accommodates fine-tuning of valve timing—typically ±4 degrees—allowing builders to compensate for camshaft grind characteristics, intake port design, or cylinder head modifications that would otherwise require custom ground cams. This flexibility becomes especially valuable when pairing new cam profiles with existing heads or manifolds, or when chasing peak torque at a specific RPM target.

Builders restoring or upgrading small-block Chevy V6 engines—whether for street performance, off-road durability, or sustained track use—benefit from the control this kit provides. The billet timing set eliminates chain stretch variability common in OEM roller chains, ensuring consistent valve timing over the engine's service life. Proper timing chain selection and adjustment directly impacts fuel efficiency, emissions compliance, and power output, making this an essential component for any serious small-block rebuild.
