COMP Cams 7112-BP Keyway Adjustable Billet Timing Set with Thrust Bearing for Pontiac 326-455

The COMP Cams 7112-BP is a 9-keyway adjustable billet timing set engineered for Pontiac 326-455 engines (1955–1982). Built from induction-hardened, precision-machined billet steel for both the camshaft and crankshaft gears, this timing set delivers the durability and accuracy demanded by street performance and race applications alike. This is the bulk pack (BP) version and includes a Torrington roller thrust bearing for reduced friction at the cam snout.

Key Features:

• Induction-hardened billet steel gears — both camshaft and crankshaft sprockets are precision-machined for tight tolerances and long service life
• 9-keyway crankshaft sprocket — allows cam timing adjustments in 2-degree increments, with up to 8 degrees of advance or retard
• True double roller chain — pre-stretched from the factory and heat-treated to maintain timing accuracy under street and race loads without loosening
• Heavy-duty large pin chain design — engineered for high-load race conditions and long-term reliability
• Includes Torrington roller thrust bearing — reduces camshaft thrust friction for smoother operation
• Dynamically balanced — all components are balanced before leaving the factory for precision fitment
• Compatible with Pontiac 326, 350, 389, 400, 421, 428, and 455 engines (1955–1982)

The 7112-BP is sold as a complete kit and is C.A.R.B. exempt for on-road vehicles, making it suitable for street and strip builds. Whether you're degreeing a cam for maximum performance or simply replacing a worn timing set, this COMP Cams unit provides the adjustability and strength to get the job done right.
