Sb Ford Mag-Dbl Roller Timing Set (1965-88)

The COMP CAMS SB Ford Mag-Dbl Roller Timing Set (1965-88) is a precision-engineered timing chain assembly designed for small block Ford engines requiring reliable, long-service valve timing control. This kit addresses the critical need for accurate crankshaft-to-camshaft synchronization in classic and vintage Ford performance builds, street engines, and restoration projects spanning nearly two decades of production. Built by COMP CAMS, a trusted leader in engine timing solutions, this timing set combines proven engineering with durable construction to ensure consistent performance across 1965–1988 small block Ford platforms.

The double roller chain design minimizes slack and wear compared to single-roller alternatives, delivering superior timing stability under sustained engine loads and higher RPM operation. Cast iron and billet steel construction throughout the kit—including sprockets and chain links—resists stretching and fatigue, maintaining tight valve timing tolerances over extended use. The roller bearing design reduces friction at the sprocket interface, supporting both stock and modified cam profiles while protecting against premature wear that compromises engine efficiency and reliability. This comprehensive kit includes all necessary components for complete timing chain replacement, eliminating piecemeal sourcing and ensuring component compatibility.

Engine builders, classic car restorers, and performance enthusiasts benefit most from this timing set when rebuilding or refreshing small block Ford engines to factory specifications or enhanced durability standards. Whether you're performing a routine maintenance overhaul or constructing a high-output street engine, this kit delivers the precision timing control necessary for smooth idle quality, peak horsepower delivery, and long-term reliability. The 1965–1988 compatibility range covers most common small block Ford displacements, making this solution ideal for 289, 302, 351W, and 351C applications. Installation requires standard engine work procedures; consult your specific engine manual and COMP CAMS documentation for proper timing mark alignment and torque specifications.
