COMP Cams Hi-Tech Roller Race Timing Set Undersized Chevy Big Block

The COMP Cams Hi-Tech Roller Race Timing Set is a double roller timing chain set for undersized, align-bored Big Block Chevy engines. It is made for both street performance and race builds. Each set pairs a cast iron cam gear with a billet steel crank sprocket. It is a durable, adjustable replacement for a worn timing set (also called a timing chain set or cam and crank gear set).

Key Features:

• Durable gear materials: The cam gear is cast iron. The crank sprocket is induction hardened billet steel.
• 3-bolt cam gear design: This is a double roller set for Big Block Chevy applications.
• Adjustable cam timing: The crank sprocket has three keyways. The middle keyway sets the cam at zero degrees of advance. The other two give 4 degrees of advance or retard, which helps when degreeing a camshaft.
• Heavy-duty double roller chain: The chain is pre-stretched and heat-treated. It has a heavy-duty large pin design to resist loosening in street and race use.
• Quality checked: The components are dynamically balanced and checked for run-out tolerances.
• Made in the USA by COMP Cams.
