True Roller Timing Set - BBC

The True Roller Timing Set – BBC by Edelbrock is an essential upgrade for big-block Chevrolet engine builders and performance enthusiasts seeking reliable valve train synchronization. Whether you're assembling a street engine, stroker build, or high-RPM race platform, this timing set ensures precise crankshaft-to-camshaft indexing without the wear and slop inherent in traditional roller chain systems. Edelbrock's reputation for precision manufacturing makes this component a trusted choice for both experienced mechanics and first-time engine builders tackling BBC modifications.

True roller timing sets replace the stock timing chain and gears with precision-engineered roller components that dramatically reduce deflection and harmonics under sustained load. The roller design minimizes friction losses compared to leaf-chain designs, improving overall engine efficiency and reducing parasitic drag at the crankshaft. Edelbrock engineers these sets to maintain tight tolerances across temperature cycling and extended high-RPM operation, preventing the timing drift that can compromise combustion events and trigger detonation in forced-induction or high-compression builds. The compact 6.5 x 10.6 inch footprint integrates seamlessly into standard BBC block envelopes without requiring frame or accessory modifications.

This True Roller Timing Set suits BBC engines ranging from 396 to 502 cubic inches and remains compatible with both naturally aspirated and supercharged applications. Installation requires standard engine bay access and basic timing tool familiarity; most professional shops or experienced hobbyists can complete fitment during a full engine teardown or rebuild cycle. The 3.85-pound assembly weight keeps rotating mass minimal, further enhancing responsiveness in performance-oriented platforms. Select this upgrade if you're prioritizing longevity, reliability, and consistent ignition timing across thousands of load cycles.
