COMP Cams Billet Timing Set CB -.010in 9 Keyway Adjustable

If you're rebuilding the front end of your Big Block Chevrolet engine, getting the timing right is crucial for performance. This COMP Cams billet timing set is designed for engines like the 396, 427, and 454, and it's specifically sized for crankshafts that are .010 inch undersize. It features precision-machined steel billet gears that are induction hardened for serious durability, making it a solid option for both street performance and race applications.

What really sets this set apart is the 9-keyway crank sprocket. This gives you the ability to make 2-degree incremental adjustments to your timing, allowing for up to 8 degrees of maximum advance or retard. This fine-tuning capability helps you dial in your engine's power delivery. It also includes a pre-stretched, heat-treated double roller timing chain with heavy-duty large pins for reliable operation, and a Torrington roller thrust bearing to keep friction down.

This timing set fits a wide range of classic Chevrolet and GMC vehicles from the late 1960s, including models like the Chevrolet Chevelle, Impala, and Camaro, as well as GMC C/K series trucks. Make sure to check the fitment details to confirm it's the right set for your specific application.
