True Roller Timing Set - BBF

The True Roller Timing Set - BBF from Edelbrock (Model 7830) is a precision double roller timing chain assembly engineered for Big Block Ford engines requiring reliable valve train synchronization and extended service life. Designed for builders and enthusiasts who demand consistent performance from high-revving or modified BBF powerplants, this kit addresses the wear and slack inherent in stock timing chains, which can lead to ignition timing drift and reduced reliability under sustained load or boost.

This timing set features cast iron and billet steel construction with a performer-link double roller design that minimizes friction and chain stretch compared to single-roller setups. The keyway adjustable design permits fine-tuning of cam timing relative to crank position—a critical feature when running aftermarket camshafts, superchargers, or nitrous systems where stock timing curves no longer apply. Double roller chains distribute load across four contact points rather than two, dramatically reducing wear rates and extending chain life by 50% or more, while the premium materials resist corrosion and thermal fatigue in high-temperature engine bays.

Ideal for Big Block Ford rebuilds, restorations, and performance upgrades, the True Roller Timing Set - BBF is most beneficial when pairing a new or reground camshaft with fresh heads or block work. Installers should verify Big Block Ford compatibility and confirm that existing sprockets and cover hardware suit the kit's geometry before ordering. This assembly delivers the precision timing control and durability expected in street and strip applications where consistency defines the difference between a reliable powerplant and a problematic one.
