Bbc Magnum Double Roller Timing Set (1965-91)

The COMP Cams BBC Magnum Double Roller Timing Set (1965–91) is a precision-engineered timing chain assembly designed for big block Chevy engines requiring reliable valve train synchronization. This double roller timing set combines cast iron and billet steel construction to deliver the durability and accuracy demanded by high-performance engine builders and restoration specialists working with classic BBC powerplants.

Double roller timing chain sets reduce deflection compared to single-roller designs, which translates to more stable crankshaft-to-camshaft timing under the stress of sustained RPM. The hybrid cast iron and billet steel construction balances cost-effectiveness with the wear resistance required in engines subjected to regular use or performance driving. COMP Cams' Magnum line is engineered to OEM specifications while accommodating the typical tolerances and clearance requirements of both stock restorations and mild to moderate performance builds. The kit includes all necessary components for a complete timing chain installation, eliminating the need to source individual pieces.

This timing set is suited for BBC engine rebuilds spanning 1965 through 1991 model years—a span that covers both original muscle car restorations and later performance applications. Whether you're refreshing a vintage big block for show-quality authenticity or assembling a street engine that demands precision valve timing, the BBC Magnum Double Roller Timing Set provides the mechanical foundation for consistent performance and longevity.
