Bb Chry Mag-Dbl Roller Timing Set (1956-79) S/b

The COMP Cams Bb Chry Mag-Dbl Roller Timing Set for 1956–1979 small-block Mopar B and RB-series engines delivers precision timing control with a double-roller chain design built to withstand sustained high-RPM operation. This kit combines cast iron and billet steel construction to maintain critical valve timing accuracy under demanding driving conditions, whether for street performance, classic car restoration, or competition applications.

Double-roller timing chains offer superior load distribution compared to single-roller designs, reducing wear on the sprockets and crankshaft snout during high-load situations. The combination of cast iron and billet steel components ensures durability while maintaining proper chain tension and alignment. This timing set is engineered specifically for Mopar B and RB-series applications, ensuring compatibility with the original equipment geometry and mounting points on vehicles from 1956 through 1979.

Builders and restorers working on classic Dodge, Plymouth, and Chrysler models with small-block Mopar engines rely on this timing set to restore proper engine synchronization or upgrade worn original equipment. Whether replacing a stretched or damaged timing chain on a 340, 360, or early big-block derivative engine, this Magnums-series kit provides the precision and longevity required for reliable operation. The complete kit arrives ready to install, reducing downtime and ensuring accurate valve event timing.

COMP Cams has established a reputation for manufacturing timing components that balance OEM compatibility with performance durability. The Magnum designation identifies this as a premium offering within the small-block Mopar market, where timing accuracy directly impacts engine longevity and drivability across idle, cruise, and full-load conditions.
